Does that mean that speaking about our personal belief, should only happen together with those we already know have faith, and less about "converting non believers"
Is it better to let curious atheists come to us when they want to know what we believe?
When you meet somebody for the first time, why would you want to tell them about your beliefs, or ask them about theirs? Isn't it enough to learn their name, shake their hand, and then -- after a little small talk -- see where the relationship goes?
I never ask anybody about their religious beliefs, even after I've known them for years. In fact, I don't ask people about their political beliefs, either. I figure they have the right to vote as they'd like, just as I like to think I do, too.
Think about being out at a sports bar, and being introduced to somebody by a friend. There's a baseball game on, and while you may be very interested in the game, you notice that the fellow you were just introduced to isn't really watching very closely. Do you have to ask him his opinion of the sport, or have you already started to learn something about him? Later, maybe, when the game's over, the conversation turns to what you might eat, when you find out he's a vegetarian and there's not much on this bar's menu for him.
You see? You don't have to pry! Just spend some time talking (and listening -- you have one mouth and two ears, so use them in proportion!), observing, and waiting patiently to discover if you've anything in common. If you do, maybe the next time you meet you'll want to strike up a conversation -- but if not, perhaps you'll just politely say "hello" and move on to where people you'd rather be with are sitting.
Life is about a great big boatload more than just religious beliefs, and a healthy person isn't spending all their time trying to "figure out God." (Why would they? They are bound to fail.)
Try living and letting live. Everybody will be more comfortable. You may even find some friends.
By the way, this atheist has some very, very good friends who are believers. We get along fine, because they subject never comes up. We talk about the thousands of other things that interest us in common.
By the way, my best friend is a straight father of two beautiful children, and I'm a gay man. We deal with that dichotomy by not talking about it. What would be the point? Instead, I get to be the "crazy uncle" who buys his kids all the birthday and Christmas presents their mother would never approve of. It's quite a pleasure, actually.
