Anyway, on the off chance that you (or someone else) want a real answer:

* I decided to give God a shot and He proved himself. It's surprising the number of people that presume God doesn't exist without actually asking Him if He's there and if He cares.

* Christian theology makes a lot of sense. It provides for dignity and equality of all people. It provides for mercy and reconciliation and harmony. It provides for justice and protection of the downtrodden and wronged. It provides meaning for everyone regardless of ability or circumstances. It's simultaneously simple enough for anyone to grasp and deep enough to challenge our greatest minds.

Maybe that's not useful to you... here's a good talk Tim Keller gave at Google that can talk to it better than I can: https://www.youtube.com/watch?v=Kxup3OS5ZhQ

I'm curious. What does this response look like? I can't say I've ever seen anything which would seem to match this, and it's definitely a question I've wondered about when I was a kid falling out of a sense of faith.

That being said, the Bible does say that if a son asks for bread, his father would not give him stones. So if someone asks God to make it clear that He exists and cares, God could literally start talking out loud if He felt that was best. But that's not typically my experience. Personally, I've heard God speak through feelings of conscience, relevant scriptures, wise words from godly people, a change in my heart over the course of a prayer, or serendipitous circumstances.

I'll be honest, it takes a certain level of trust in God for any of it to make sense. If someone approaches God with a sneer, I wouldn't count on God responding. If your child or SO spitefully challenged you to prove yourself, what would you do? That being said, God has a habit of going above and beyond for me.
