I Know What I Should Do, But I Don’t Do It: Understanding the Struggle Between Knowing and Doing
Have you ever known exactly what you needed to do, genuinely wanted to change, and still found yourself doing the very thing you knew you shouldn't?
You know you need to apologize, but pride gets in the way. You know you should have a difficult conversation, but you keep putting it off. You want to be more patient with your spouse or children, but frustration gets the better of you. You recognize a habit is harmful, yet you continue returning to it.
Why does this happen?
The Apostle Paul describes this very struggle in Romans 7:15–25. He writes:
"For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate." (Romans 7:15)
Paul describes the tension between knowing what is right and actually doing what is right. He recognizes the goodness of God's law, yet he also recognizes the ongoing struggle with sin.
Christians differ on how to interpret Paul's experience in this passage. I understand Paul to be describing the ongoing struggle of a believer who desires to obey God while still wrestling with sin and the flesh.
Regardless of where someone lands in that discussion, the passage gives us an important opportunity to consider the relationship between our minds, desires, habits, choices, and dependence on God's grace.
The central lesson is this: Knowing what is right does not automatically lead to doing what is right.
Let's consider several reasons why we sometimes struggle to follow through on what we already know.
1. Knowing What Is Right Doesn't Automatically Lead to Doing It
We often assume that if someone understands why a behavior is harmful, they will change. If we explain the consequences, provide enough information, or help someone recognize the problem, we expect improvement to follow.
But human behavior is not driven by knowledge alone.
A person can know that anger damages their marriage and still lash out at their spouse. Someone can understand that avoiding difficult conversations makes problems worse and still avoid those conversations. We can recognize that a particular habit is unhealthy and continue returning to it.
Why?
Because we are not merely reasoning machines. We are people with desires.
We make decisions influenced by what we want, what we fear, what we resent, and what we believe will bring us relief. Sometimes we know the right course of action but want something else more in the moment.
A husband may know he should listen patiently, but he wants to defend himself more than he wants to understand his wife. A parent may know that a calm response is better, but yelling feels more satisfying in the moment.
James 1:14–15 reminds us that temptation is connected to our desires. We can genuinely hate the consequences of a behavior while remaining attracted to its immediate rewards.
This creates an important tension: The short-term reward of a behavior often competes with its long-term consequences.
Avoiding a difficult conversation may bring immediate relief, but it often creates greater difficulty later. An angry outburst may feel satisfying for a moment, but it can damage a relationship that takes much longer to repair.
When we repeatedly fail to do what we know is right, we should ask more than, "What do I know?"
We should also ask:
What am I wanting?
What am I avoiding?
What am I afraid of?
What am I pursuing in this moment?
These questions help us move beyond examining behavior and begin examining the heart.
2. There Is a Difference Between Motivation and a Plan
Sometimes we assume our problem is a lack of motivation. We tell ourselves, "I just need to try harder," "I need to want it more," or "Next time I'll do better."
But there is a difference between wanting to change and knowing how to respond when a difficult situation arises.
Good intentions need practical expressions.
Consider someone who genuinely wants to stop yelling. What will they do when they feel disrespected? What will happen when frustration begins to rise? What specific response will replace the familiar pattern?
Or consider someone who wants to stop procrastinating. What will they do when a task feels overwhelming? When will they begin? How much time will they spend working on it?
A plan helps us decide ahead of time what we intend to do when predictable challenges arise.
For example:
Instead of saying, "I'll be more patient," decide, "When I notice my voice getting louder, I'll pause before responding."
Instead of saying, "I'll stop procrastinating," decide, "I'll work on this task for ten minutes at 9 a.m."
Instead of saying, "I'll communicate better," decide, "When I'm tempted to withdraw, I'll tell my spouse I need time to collect my thoughts and agree on when we'll resume the conversation."
Dr. Jordan Peterson has emphasized the importance of breaking difficult things down into small enough steps that we can actually accomplish them.
This is a helpful principle. Sometimes the goal is too vague or too large. We need to make the next step specific enough to practice.
Motivation fluctuates. Sleep, stress, fatigue, disappointment, and the demands of daily life all influence how motivated we feel. If our behavior depends entirely on feeling motivated, our follow-through will often be inconsistent.
A plan does not replace heart change, but it helps put our intentions into practice.
Identify the Pattern Before It Escalates
Many people focus on the final behavior without examining the steps that lead up to it.
Consider the progression of an angry response:
Someone makes a comment.
You interpret the comment as disrespectful.
You experience frustration or defensiveness.
You begin rehearsing what you want to say.
You respond harshly.
If we only focus on step five, we may miss several opportunities to respond differently.
The goal is to identify the earliest warning signs and develop a more faithful response before the pattern escalates.
Ephesians 4:25–32 provides a helpful biblical example. Paul doesn't simply tell believers to stop sinful behavior. He also describes constructive alternatives: speak truthfully, work honestly, share with those in need, use words to build others up, practice kindness, and forgive.
Biblical change involves both putting off and putting on.
Don't simply identify the behavior you want to stop. Decide what faithful obedience will look like the next time you face that situation.
3. Competing Desires Often Influence Our Decisions
We sometimes explain our behavior by saying, "I didn't think," "I lost control," or "I don't know why I did that."
Those statements may express genuine confusion. But if we examine the situation carefully, we can often identify the desires, fears, and perceived benefits that influenced our decisions.
Here are four competing influences worth examining.
Comfort: I Want Relief Right Now
Avoiding a difficult conversation, scrolling instead of working, or giving in to an impulse can provide immediate comfort.
The problem is that short-term relief may reinforce a pattern that creates greater long-term difficulty.
Ask yourself:
What discomfort am I trying to escape?
What does this behavior provide for me immediately?
Am I willing to endure temporary discomfort to pursue something better?
Sometimes the right thing to do is uncomfortable. Faithfulness may require us to endure temporary emotional discomfort rather than continually choosing immediate relief.
Fear: I Need to Protect Myself
Fear can lead us to lie, withdraw, control others, avoid responsibility, or seek constant reassurance.
Sometimes we choose what feels safest instead of what faithfulness requires.
Consider Peter's denial of Jesus. Despite his earlier expressions of commitment, Peter denied knowing Christ when faced with the possibility of suffering the consequences of being associated with Him.
Fear of immediate consequences influenced his behavior.
We can ask ourselves:
What am I afraid will happen if I do the right thing?
Am I treating someone's disapproval as something I cannot bear?
What would faithful action look like even if I still felt afraid?
A life characterized by integrity can prevent a tremendous amount of unnecessary fear. When we are not continually hiding something, we have less reason to fear it being exposed.
Resentment: I Shouldn't Have to Do This
Resentment often communicates the feeling that something is unfair or that we shouldn't have to endure a particular difficulty.
It can make obedience feel like surrendering to an injustice.
For example, someone may know that forgiveness is necessary but continue rehearsing an offense because anger feels like a form of self-protection or a demand for justice.
We need to distinguish legitimate recognition of wrongdoing from nurturing bitterness or seeking revenge.
Forgiveness does not require denying harm, removing appropriate boundaries, or abandoning accountability. It does, however, involve a posture of heart that seeks to trust God and respond with truth and love rather than being controlled by bitterness.
Ask yourself:
What am I holding onto?
Am I seeking justice, or am I nurturing bitterness?
What would it look like to respond faithfully without pretending the wrongdoing never happened?
A Good Desire That Isn't the Best Desire
Sometimes the conflict isn't between something good and something obviously bad. It is between a legitimate desire and the way we choose to pursue it.
We may want a peaceful marriage but also want to win an argument. We may want financial stability but also want the newest game or another unnecessary purchase. We may want to serve others but also want someone to recognize our contributions.
The desire itself may not be wrong. The problem is that we have elevated it above something more important.
Ask yourself:
What am I prioritizing in this moment?
What good thing have I elevated above its proper place?
What am I willing to sacrifice to get what I want?
There is no life without sacrifice. We regularly give up something we enjoy in order to pursue something better.
Jesus said in Mark 8:34 that anyone who would come after Him must deny himself, take up his cross, and follow Him. Following Christ involves surrendering our own preferences and desires to something greater.
When you find yourself struggling, consider asking three questions:
What am I feeling?
What am I wanting?
What response would honor God in this situation?
These questions can help us move beyond simply describing our behavior and begin examining what is happening within us.
4. Lasting Change Involves the Heart, Habits, and Renewing of the Mind
Romans 7:22–23 describes Paul's delight in the law of God while recognizing the conflict of sin within him.
This reminds us that lasting change involves more than suppressing unwanted behavior. It involves learning to think, desire, and act differently.
The heart matters because our behavior is connected to what we love and value. Scripture doesn't treat the heart as merely the seat of our emotions. It is central to our thinking, desires, intentions, and decisions.
Proverbs 4:23 tells us to guard our hearts because the course of life flows from them.
So rather than asking only, "How do I stop this behavior?" we should also ask:
What beliefs or interpretations are influencing my behavior?
What am I wanting from this behavior?
What desire is ruling my response?
Habits matter, too. Repeated choices can reinforce patterns until certain responses become almost automatic.
A person who regularly withdraws during conflict becomes increasingly practiced at avoiding uncomfortable conversations. A person who regularly pauses, listens, and responds thoughtfully can develop a more constructive pattern over time.
As Kevin DeYoung has expressed, holiness is the sum of a million little decisions.
Our daily routines and repeated choices can make certain responses easier to practice. Prayer, Scripture meditation, planned conversations, accountability, and appropriate physical care can all support a life of greater faithfulness.
These practices are not substitutes for spiritual renewal. They are practical ways of pursuing obedience.
Discipline Is Not the Enemy of Grace
Some Christians treat discipline and grace as though they are opposites. But biblical grace does not teach passivity.
Titus 2:11–12 teaches that God's grace trains us to renounce ungodliness and live self-controlled, upright, and godly lives.
Discipline cannot save us, and sheer willpower cannot conquer every struggle. Yet the Christian life includes intentional effort, perseverance, and obedience as we depend on God.
We do not practice spiritual disciplines to earn God's love. We practice them as people who depend on His grace and desire to grow in godliness.
Romans 12:2 calls believers to be transformed by the renewing of their minds. This involves more than replacing a negative thought with a positive one. It means learning to evaluate our assumptions, desires, and circumstances in light of God's character and His Word.
For example, an old way of thinking might be:
"If someone criticizes me, I must defend myself immediately."
A renewed perspective might be:
"I can listen to criticism without retaliating. I can consider whether it is true, respond with humility, and make changes where necessary."
The goal isn't to deny reality or manufacture positive feelings. It is to respond to reality with truth, wisdom, and faith.
5. Pursue Change Without Depending on Feelings or Falling Into Legalism
One of the most important parts of Romans 7 comes in verses 24–25:
"Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord!"
Notice Paul's question. He doesn't simply ask, "How can I become more disciplined?" He asks, "Who will deliver me?"
His answer is Jesus Christ.
The Christian understanding of change is deeper than simply becoming more self-aware, creating better routines, or trying harder. Those things can be helpful, but our ultimate hope is found in Christ.
There are two opposite errors we should avoid.
The first is believing we can transform ourselves through sheer effort. This turns obedience into a performance-based system in which every failure becomes evidence of our worthlessness.
The second is believing that because we depend on grace, intentional effort is unnecessary. Grace does not mean making peace with patterns that harm us, harm others, or contradict God's Word.
Legalism distorts the relationship between obedience and God's acceptance. It treats our performance as the basis for earning God's favor.
But salvation is by grace. Our identity is grounded in Christ, not in our ability to perform perfectly.
At the same time, grace should lead us toward repentance and growth rather than complacency.
When we fail, a faithful response might include:
Acknowledging our behavior honestly.
Taking responsibility rather than shifting blame.
Confessing our sin to God.
Making restitution where appropriate.
Identifying what contributed to the failure.
Taking concrete steps toward a different response.
Depending on God's grace rather than treating failure as the final word about who we are.
Romans 8 continues the discussion by declaring that there is no condemnation for those who are in Christ Jesus. Paul then describes the work of the Spirit in the believer's life, including putting sinful deeds to death.
The movement from Romans 7 to Romans 8 is important. We recognize the reality of our struggle, but we do not leave ourselves without hope. We look to Christ, depend on the Holy Spirit, and continue pursuing obedience.
Feelings Are Real, but They Are Not the Final Authority
Our feelings provide information. They can function like alarm systems, alerting us that something is happening internally or around us.
But alarms don't tell us what to do. They simply alert us to something that needs attention.
You may not feel like apologizing, but you can still recognize that you were wrong. You may feel anxious about an important conversation, but you can still speak truthfully and lovingly. You may feel discouraged after a failure, but you can still confess, seek help, and begin again.
Faithfulness does not require waiting until our feelings change before we take the next right step.
The question becomes: What would faithfulness look like if I didn't wait for my feelings to change first?
6. A Practical Framework: Moving From Knowing to Doing
How do we begin putting these ideas into practice?
Here is a simple five-step framework for applying the principles we've discussed.
1. Recognize the struggle.
What am I repeatedly doing that conflicts with what I know is right?
2. Examine the heart.
What am I wanting, fearing, avoiding, believing, or trying to control?
3. Renew the mind.
What truth from Scripture challenges my assumptions and directs my response?
4. Plan the next action.
What specific, realistic act of obedience can I take when this situation arises again?
5. Depend on grace and persevere.
How can I respond to failure with honest repentance and renewed dependence on Christ rather than despair or self-righteousness?
This framework helps move us beyond simply identifying a problem. It gives us a way to think about the heart, apply Scripture, make practical plans, and continue growing through dependence on God's grace.
Don't Settle for Knowing What Is Right
Perhaps one of the most frustrating experiences in life is knowing what you should do and repeatedly failing to do it.
But recognizing that struggle is an important starting point. We should not confuse understanding a problem with solving it, or wanting to change with having a plan for change.
We need to examine our desires, recognize the patterns that influence our behavior, develop practical responses, and pursue obedience even when our feelings are not cooperating.
Most importantly, we must remember that we are not our own saviors. Our hope is not in perfect discipline or flawless performance. Our hope is in Jesus Christ, whose grace both saves us and teaches us to live differently.
Here is the question to consider this week:
What is one thing you already know you need to do? And what is one faithful step you can take toward doing it?
Don't settle for knowing what is right. By God's grace, take the next step toward living it.
