Don't you find it amazing that God's Word tells us He "remembers our sins no more"? Can we actually "forgive and forget" like that? Scripture says to "forgive others as the Father forgives us", so it's certainly possible. It all hinges on who is doing the forgiving, you or the perfection in you! Be blessed by this short teaching.
God throws our past, present, and future sins into the sea of forgetfulness when we make His Son our Lord and Savior. Can we forgive and forget like that? When you know that you know who lives inside you, that answer becomes very clear!
