"The Son of Man has authority on earth to forgive sins.” Luke 5:24
Because he knows the end of the story.
“This is my blood of the covenant, which is poured out for many for the forgiveness of sins.” Matthew 26:28
“Your sins are forgiven,“ were very costly words.
"Do not say to your neighbor, ‘Go, and come again, tomorrow I will give it’—when you have it with you.” Proverbs 3:28
The disinclination to give.
The deception that you don’t have access.
The hope he will not return.
None of this shows God is your treasure.
