Yes, I would agree that an a should have caused him to reconsider his ways. I'm sorry I didn't understand that he was a christian but since he is not practicing does he still believe in God? And why won't he go with you to church?
Anyway, I digress. Ok so you've listed some things you do to try to get him moving. Can you do a 180 on what you 'normally' do? What are some things you HAVEN"T tried? Like the things that scare you to do because you think they won't work?
