If You, Lord, kept a record of sins, who could stand? (Psalm 130:3)
Jesus came in the flesh to put away sin by the sacrifice of Himself (Hebrews 9:26).
God does not count sins against anyone in the world during this age. (2 Corinthians 5:19)
Those who refuse to trust Jesus store up wrath for themselves for the day of judgement in the next age. The sins that Jesus "put away" are returned to them. (Romans 2:5)
Those who trust Jesus enter into an eternal covenant of peace with Him that He made through the blood of His cross. (Colossians 1:20, Matthew 26:28, Isaiah 54:9-10)
To those who trust Him God says, "I will never remember your sins and lawless deeds" (Hebrews 10:17, 8:12). God takes their sins away forever (Romans 11:27, Psalm 103:12), freeing them from sin (Romans 6:6,7,18,22, 8:2), cleansing and purifying them from their sins forever (Hebrews 1:3, 13:11-12, 1 John 1:7,9).
Blessed is the person whose sin the Lord will never take into account! He will never charge that person with sin! (Romans 4:8)
