“Why do I struggle with the same sin over and over again, and how can I break the cycle?”

Someone submitted this question not too long ago. I could feel their discouragement through the email. Have you ever felt stuck in a cycle of sin, seemingly unable to break a pattern that dishonors the Lord and reaps a harmful harvest?

I know I have, and when I do, my mind immediately jumps to Romans 7. “For I have the desire to do what is right, but not the ability to carry it out. For I do not do the good I want, but the evil I do not want is what I keep on doing.” (vv. 18-19)

So what do we do when we hit that wall? I think Romans 7 provides us with some practical steps and encouragement to break the cycle of sin.

The first is this: Don’t sign a premature armistice agreement with our sinful nature.

As believers, the Bible declares that our heart of stone has been removed and replaced with a heart of flesh (Ezekiel 36:26). Yes, we are new creatures, and yes, the controlling power of sin over us has been broken ... but the presence of sin remains.

I think many of us have seriously underestimated the drama, the power, and the depth of remaining sin—how deep it is inside of us and how it infiltrates every aspect of our being. There is a tremendous moral and spiritual war still raging on within us.

I am surprised by how many Christians, myself included, live with a peacetime mentality. While we might be active fighting our culture or protesting outside evil, some of us seem to expect the luxuries and leisure of peace in our heart—where the war rages most fiercely.

And then suddenly, we get surprised or discouraged when sin starts winning!

Don’t misunderstand: because of the wonderful atoning work of the Prince of Peace, the war between God and us has ended. And when Christ returns, our struggle with sin and the Enemy will be complete. But until then, a battle of hostility inside us still rages. Perhaps the problem is that we think that the adversary within—remaining sin— has been conquered long before it actually has.

In the middle of this spiritual war, there’s a second thing you must do: Don’t argue for your own righteousness.

Perhaps the biggest and most tempting lie that all of us tend to embrace is that our most significant problems exist somewhere outside. This is partially true because, in a fallen world, people sin against us and we experience bodily pain and suffering. The Apostle Paul experienced both of these and doesn't minimize them by writing about them elsewhere in Scripture, but in this particular passage, he's only concerned about his own sin and heart. He doesn’t argue for his righteousness.

On the contrary, in Romans 7, Paul locates his struggle inside himself. He knows that when you argue for your righteousness, you convince yourself that you don’t need the grace of God—the only thing that can protect you from sin.

“If we say we have no sin, we deceive ourselves, and the truth is not in us.” (1 John 1:8)

Are you feeling discouraged in your battle with sin? At first glance, Romans 7 can be a pretty discouraging passage! Paul exclaims, “What a wretched man I am! Who will rescue me from this body of death?”

But the passage doesn’t end there: “Thanks be to God—through Jesus Christ our Lord!”

Eternal rescue has been supplied, but rescuing grace is still necessary every day. What we have received in Christ, we still desperately need. Romans 7 calls us to be aware and serious; the war for our hearts is not over. Our need for a conquering Savior has not ended.

God bless,

Paul David Tripp

Reflection Questions

1. What sin have you conquered or left behind by God’s grace since becoming a believer? How have you become a new creation by being in Christ?

2. What sins or weaknesses do you find yourself still struggling with? When was the last time you wrestled with the flesh because of it? What was the outcome? Do others know of this consistent battle?

3. Are you more committed to fighting the sins of the culture than you are fighting remaining sin in your heart? Why is the latter more of a danger to you?

4. Consider a recent time when you deceived yourself by arguing for your own righteousness. Who, or what, did you blame? How did you justify your selfishness or sin?

5. What does the daily rescuing grace of Christ look like in your life? How can you pursue it today? Be specific.
