When we come to Christ we get to start our lives all over again. All clean and pure. This is so that we can worship and walk with God. But also, after we are in Christ, every time we sin, we get to go to God and start all over again. But what this means is that we need to extend this same grace to others and let them start over again. And, if we refuse to forgive them, it shows that we might not have actually believed that God has given us this great gift.
