God is the God of do-overs, and that should give us great hope. We really can be absolved of our past.
From Acts 22:6-8: “[From the conversion of Paul] While I was on my way and approaching Damascus, about noon a great light from heaven suddenly shone about me. I feel to the ground and heard a voice saying to me, ‘Saul, Saul, why are you persecuting me?’ I answered, ‘Who are you, Lord?’ Then he said to me, ‘I am Jesus of Nazareth whom you are persecuting.'”
