No, true repentance means we stop sinning. And when we sin we need to confess it and ask for forgiveness.
(1 John 1:8-10 NIV) If we claim to be without sin, we deceive ourselves and the truth is not in us. {9} If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. {10} If we claim we have not sinned, we make him out to be a liar and his word has no place in our lives.
The Saints (who are sinners in this life but have faith in Jesus) will be purified after the resurrection and entrance into heaven. We will be scourged for our sins in this life. Again, but purified in the next.
No where do I contradict that scripture in anything I wrote. I say admit you’re a sinner the NIV says confess your sins; forgiveness is by faith in Jesus. You misconstrue it to think you can stop sinning; that contradicts the scripture you presented. @barncat
