So let me get this right - he gambles - and then tithes it - Id love to hear the priests rationalization in being the recipient of gambling proceeds.
Hebrews 13:5
Keep your lives free from the love of money and be content with what you have, because God has said, "Never will I leave you; never will I forsake you."
I wouldnt wish the curse of big money on anyone. It is often a destructive, deadly force.
God fill this man with the supernatural strength needed to turn from this gambling sin.
