What is disheartening about knowing why I believe in God? Faith without evidence is not faith, it is presumption. Why can't I just have faith in the flying spaghetti monster? Wouldn't that be just as rational as believing in the God of the Bible? If I am supposed to have faith according to the atheist idea that faith is belief without any evidence, then yes it would be just as rational, which would be not rational at all. The evidence that I have which outweighs any evidence to the contrary is the Bible itself and its divine prophecy. No other book can make the claims that the Bible does and back it up.
Isaiah 41:21-24
21 Produce your cause, saith the LORD; bring forth your strong reasons, saith the King of Jacob.
22 Let them bring them forth, and show us what shall happen: let them show the former things, what they be, that we may consider them, and know the latter end of them; or declare us things for to come.
23 Show the things that are to come hereafter, that we may know that ye are gods: yea, do good, or do evil, that we may be dismayed, and behold it together.
24 Behold, ye are of nothing, and your work of naught: an abomination is he that chooseth you.
In these last days, the fact that there is a nation of Israel in their land making preparations to rebuild their temple, and with the stage being set for a one world government, ought to set any reasonable man to trembling before God.
But this also is foretold.
2 Peter 3:3-4
3 Knowing this first, that there shall come in the last days scoffers, walking after their own lusts,
4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
