I will go to my father and say to Him: Father, I have sinned against You.
Luke 15:18

We say:

I made a big mistake. I wish it would not have happened. I know they will never forgive me. Maybe now God
is punishing me.

God says:

Lord, if you held our sins against us then nobody could stand.
Psalm 130:3

He has not punished in the way that our sins deserve to be punished.
Psalm 103:10

Father, I really did it this time! I do not deserve to be forgiven but I remember You said that if we confess what we have done we will be forgiven.

Help the ones I hurt to forgive me also and show me how to humble myself and ask them even if they do not forgive me. I cannot live this way so I am
trusting You about this thing.
