We have a strange illusion that mere time cancels sin. But mere time does nothing either to the fact or to the guilt of a sin. – C.S. Lewis

We have all become like one who is unclean, and all our righteous deeds are like a polluted garment. We all fade like a leaf, and our iniquities, like the wind, take us away. (Isaiah 64:6 ESV)

For while we were still weak, at the right time Christ [who was delivered up for our trespasses and raised for our justification (Romans 4:25 ESV)] died for the ungodly. (Romans 5:6 ESV)

For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life.
(Romans 5:10 ESV)

God shows his love for us in that while we were still sinners, Christ died for us.        (Romans 5:8 ESV)

Whoever conceals his transgressions will not prosper, but he who confesses and forsakes them will obtain mercy.
(Proverbs 28:13 ESV)

But thanks be to God, who gives us the victory through our Lord Jesus Christ.
(1 Corinthians 15:57 ESV)
