Well, unfortunately I haven't seen it. As I recall, Jesus also said "Though ye not believe me, believe thy works". I would believe the works, if such existed that are unexplainable by any science and are tangible.
Personally, the original reason I believed in God is that an adult told me he existed when I was little and, being little, I took their word. But over time, I've listened to people talk about their experiences with God and seen it with others. I think I've seen Him get me through a lot of stuff the past few years that I don't think I'd have been able to make it through alone. You could say that I got through them because I worked hard, or just because believing in a higher power has some effect psychologically, or that there were coincidences involved, but when I put it all together, those reasons just don't work for me. But if I had to give just one reason that I believe God is real, it would be that He told me so. Audibly.
Congrats to you. Sadly, no such revelation has occurred to me.
I'm technically agnostic, but I lean toward there not being a God. I used to believe in God, but then I started asking others what their reason was to believe in God. They didn't have a good reason, then I realized I didn't have a good reason, and stuff happened from there.
