Seriously. You do NOT want to learn about God from this forum. Ask your questions to a pastor you trust. (And phones work, even if parents won't let you walk to the church.)
The pastor may introduce you to someone he trusts to keep helping you, but to trust everyone on this site? It's like knowing you have to walk through a dark scary alley at night and pulling the first person you meet along the way to guide you. It is possible that person will truly guide you. But it is just as possible that's the person you're afraid you'll meet in that alley!
There are safe people to hang with on this site, but don't confuse that with thinking this site is safe. It's not. (Nothing personal against the site, but when you open it up to anyone who claims to be a Christian, that's exactly what you get!)
