I'm confronted with this problem alot and i handle it as best i can. I was wondering how you handle it...

Someone who either: Doesn't believe in God, Believes in another religion, or is a skeptic of Christianity comes up to you and starts questioning your beliefs and getting offended when you talk about God. (not like mad just more argumentative).

I have found myself confronting people who used to believe in God and then being offended by my spirituality. I've been asked questions like "well how can you believe in someone you can't see, or feel, or get tangible signs from?" and "How can you leave your life in his hands?" and "shouldn't you learn to lead your life and not seek happiness through a God?" and i've been told such things as "only the weak need a God" and "only people who can't stand for themselves spend their life seeking happiness through a supernatural being."

how do you deal with a situation like that?
