God exists whether or not you choose to believe.  Many people do not believe because it would force them to face the fact that they need to be accountable to such a God. Most of those who take refuge in atheism or agnosticism do so because it is a convenient escape from the stern reality that man is accountable to anyone. It is usually not so much a case of "I cannot believe" as it is a case of "I do not want to believe."

A good detective could tell you many things about my skills, habits and character just by examining something I may have made or handled.  A great deal could also be learned about God by a careful examination of the universe, the work of His hands. The important point is that the detective who examines only what I make can never say he knows me.  He may know some things about me, but before he can say that he knows me, there must be a process of revelation: I must communicate with him.  I must tell him what I think, how I feel and what I want to do. Only then does it become possible for him to know me.  Just so, if God is ever to be known and His thoughts, desires and purposes perceived, He must take the initiative and make at least a partial revelation of Himself to men.

Of all the many books in this world, the Bible is the only one that claims to be a direct revelation from God, telling us of Himself and His purpose for us.  The Possibility that the Bible is a book of such importance demands a  worthy and thoughtful investigation.  So, with the advice of Francis Bacon neither to accept nor reject, but to weigh and consider.
To be fair to ourselves and to the Bible, we should read it through.  As a judge must not make his decision when the case is half heard, neither must we.  Rather, like the judge, we should compare the evidence of the witnesses, and weigh and consider every work, seeking its deepest significance rather than  accepting its surface meaning.  Surely, the importance of the Bible's claims justifies spending the necessary time on the study of its 66 books, which were written by at least 40 different writers over a period of 1600 years, in places as far apart as Babylon in Asia and Rome in Europe.  With such authorship one would expect to find a miscellaneous collection of contradictory statements.  Its unity is therefore especially striking, for each contribution is the complement of the others.

In my consideration of this whole matter, slowly the truth of 2 Peter 1:21 became certain to me.  There was no other reasonable explanation.  "Holy men of God spake as they were moved by the Holy Ghost."  This belief was confirmed as I read prophesy after prophesy in the Old Testament, which found their fulfilment, down to the letter, hundreds of years later. For instance, Isaiah 53:1-12 foretold the death of Christ with minute accuracy, 700 years before His crucifixion!  Yes, the difficulties in the way of doubting the Book seemed to me greater than those in the way of believing it.  The problems were all on the side of unbelief!
