The starting point for this encouragement/speech is Psalm 103, which says, among other things, that God does repay us for our sins.
Some think: God will not answer my prayer or help me if I should do a sin. But God does not punish you for sins you do, have done or will do.
Sin we will most likely punish you in one way or another, but it is not God’s punishment.
God’s goodness is better than you think!
