I don't think you should really try to educate the person or push it on them so much. Remember God is a gentlemen, he wont force himself on you, he's patient. Just slowly express to the person how God is in your life and be an example. Thats always the best way, they can't really come down on you and how God is in your life because you don't come down on them for not having God. I hope I made sense. All and all, just be an example.
