Repent From Dead Works, Not Sin

"For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins." (Hebrews 10: 2)

We cannot keep working steps or doing religious duties in order to purge from us a sense of guilt and shame.

Because of all that Jesus did at the Cross, we are called no longer to repent from sin, but rather from dead works:

"Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God" (Hebrews 6: 1)

and then

"How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?" (Hebrews 9: 14)

Sin is not going away as long as we walk around in these bodies.

"21I find then a law, that, when I would do good, evil is present with me. 22For I delight in the law of God after the inward man: 23But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members." (Romans 7: 21-23)

We will get new bodies when we are resurrected, but in the mean time, we are called to rest in the grace of God, and recognize that Jesus died for all our sins and condemned sin in the flesh, as well:

"1There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. 2For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. 3For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: 4That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit." (Romans 8: 1-4)

Take another look at Hebrews 10: 2.

Because of what Jesus did at the Cross, there is no more conscience of sins:

"14For by one offering he hath perfected for ever them that are sanctified." (Hebrews 10: 14)

We have  a perfected standing in His righteousness before God the Father because of His Son, so repent from dead works, like confessing sins or improving your mood to make you right before God. He has taken care of all things in His Son.
