How do you know prayer doesn't work?
"Because I'm bald!"
-Larry David
This is a logical fallacy for many reasons, such as, but not limited to:
-Larry David does not accept Jesus Christ as his Lord and Savior, thereby consciously self sabotaging any prayer he may have done. (John 14:13-14, John 15:7, 1 John 5:14-15, Acts 4:12, Romans 10:13)
-Maybe one or more Christians have prayed for Larry to go bald, perhaps his wife is Christian and prayed to find a wealthy bald husband she can easily control.
-Maybe his baldness are the wages of his sins, only those who are saved through Christ Jesus are blessed by not being reckoned the wages of their sins (Psalms 32:1-2, Romans 4:7-8)
