How do I convince my husband that not going to church with him is not personal rejection ?

Personally if he is your Husband and you are the Wife; you should support him and go whether you "want" to or not. That simply makes you sound like a rebellious child like "I'm not going" and stomping your foot. The only advice I can offer is to support him even though you aren't going and inform him that because you both didn't go before marriage then he should understand that it's not something he should expect out of you. However, it's not like he's asking you to walk through fire or join a cult...something that would be rediculous of him. You may find him annoying by being "religious" just as he finds you annoying for not understanding that he only wants what is best for you and knowing that if he is saved he will go to Heaven and he wants you to go with him. He knows if you refuse Christ for whatever reason you will go to hell....this is probably why he is sad, not taking it personally. In the end he will win with Christ anyway; it's not like he has anything to loose by making this decision; only you. So that may be where he is upset. Try being a little more open minded. Go to church at least once or twice before refusing to go forever.
