Hello, welcome 
You could invite him to the forum if you like. I have lots of videos on these kinds of topics if they would be helpful, I can give you the links.
I agree with Losty, actively going at someone to deconvert them is generally a bad idea. Discussion is fine, as long as it's mutually agreeable. But if you're always starting it and he's not interested, it's only going to worsen your friendship.
Best to let him know he can talk to you, and let him approach you with questions. This has always been my strategy, and it has served me well for a variety of subjects.
