God doesn't expect us to be perfect or to earn our forgiveness. He gives it freely to us through His Son. Jesus came to earth and died for all sin. Our sins are already covered, we just have to ask forgiveness. God shows how much He loves us by forgiving us even though we can't earn it. We are not perfect and that's OK!
No one is perfect, but you can be forgiven!
Prayer:
Dear God-
Please forgive me for all of my sin. Help me to live a better life by following You. Through Jesus, my Redeemer, I pray, amen.
