Gringo......take a look at the world around you. If the famines, floods, pestilence, etc. don't point you to a judging hand of God, nothing will. The Bible says that some of us are saved from fear, because we are scared of the coming judgment. It also says that some of us are saved because of the compassion of others. If you do not fear the Lake of Fire, I hope that someone shows you enough compassions that it draws you to our loving Heavenly Father.
As for believing without seeing....well, that is what faith is all about. I have never, ever seen a million dollars, yet I believe that it does exist, because I see the evidence of it. I have never seen God, but I know He exists because of the evidence I see.
