The argument for order and design, I believe is a great starting point for why believing in God of the Bible is true.
Plato started this argument in seed, but it came to popularized by Williams Paley in the late 18th century with his watchmaked analogy.
You're walking across a field and stub your toe on a stone. If we were to wonder how the stone came to be there, it would not be hard to imagine that the stone had always been there. But if we came to stub our toe on a watch lying in the field, it would be difficult to believe it was "just there." The watch is intricate and every part is necessary for a specific purpose. It would be absurd to deny that the watch had an intelligent designer, a wacthmaker. Paley argued that the world shows evidence of purpose, and therefore, an intelligent designer.
A variation of this looks at the human race. Does it make sense to believe that thinking, feeling, imaginative, aesthetic creatures such as humans come from a mechanism such as blind chance? Can impersonal forces give rise to personal beings? A designer who is personal (thinking, feeling, moral etc) is the only adequate explanation for the existence of humanity.
So, thus far, if you believe this argument to be satisfactory, you believe in a personal, moral, intelligent and even loving God. Why create everything if not for His purpose and pleasure?
And He'd want to communicate with His creation. What better way than through written word? It stands the test of time and is transferable.
So, without leaping very far at all, to believe that God exists, is personal, loving, intelligent, and has made himself known through written word among other things is a reasonable conclusion.
The reasons continue to prophecy, experience, reliability in the Bible versus other scriptures, and others.
At the very least, my goal is to get you to see that belief in the God of Abraham is not quite so far the "leap of faith" that our culture would have you believe. Do I strike you as the ignorant, crutch-needing, weak-minded fool that society would have you believe Christians are?
