Signs are not need. You just need to use the same logical reasoning you use to believe any other thing. For example, do you believe there was a man called Alexander the Great? OK how about Abraham Lincoln? Well, the same why you find out about these guys, try finding out about a man named Jesus. No signs need.

Look at it this way, you live in a country and you have to obey the country rules, right? If you don't, you get put in jail. Well, you live in God's world and he has his rules for living in his world, just like the country you live in has its rules. So same way as in whatever country you live, if you break the rules of God, you get thrown in jail aka hell.

Better yet, you post on VGChartz and you must abide by the rules right? Why don't you try breaking the rules on VG Chartz and see what happens. Same way, you break God's rules there are consiquences. 

If you believe there was a dude named Alexander, you must also believe he was great. Meaning that you either accept entirely who Alexander claims he was or you don't believe in him at all. Same with Jesus you either believe the whole man or not. Or do you believe there was a man called Abraham Lincoln, but don't believe he was a US President? Or do you in fact need a sign, or need to see him walk on water for yourself?

It's funny how non-christians think they can debate Christians about God and spiritual things and win, lol. That's kind of like a non-gamer debating a gamer about video games and expect to win. ha ha

So Jews, Muslims, Hindu's and all the others can't debate about god and win?

Correct! If you don't believe me, go find one of each and bring them. Or bring your Jew, Muslim and/or Hindu facts and let's do this.
