The saints of scripture have their sins recorded for all generations to come.
Abraham slept with Hagar to fulfill God's promise in his own way.
Moses struck the rock at Meribah in his distrust and misrepresented God.
David had an affair with Bathsheba when his army was out at war.
These are recorded for us in this age so that we can learn from their mistakes.
But on that day when the new heaven and new earth meet our resurrected bodies, our Great God will remember their disobedience no longer. And if God chooses to remember no more, than we also will remember no more.
That is how it will be on the wedding banquet of the lamb. Your sins will have been blotted out and removed from you as from as the east is from the west. You will be perfect as your heavenly Father is perfect and you will be as free and innocent as a child of heaven.
Hallelujah and Amen!
