Even if some people do believe in God simply because they want to, this in itself does not prove or disprove God's existence.  You cannot infer from a psychological state to the proof or disproof of any alleged fact. Sometimes people do believe things because they want them to be true. They also believe things (or refuse to believe them) because they want them to be false.

The truth or falsehood of God's existence rests on facts and evidences beyond the emotions and desires of my heart and yours.

Sometimes people deny God's existence because they don't want to have to face Him if indeed He does exist.  I understand that apprehension, but if He does exist, and if He wants your attention, you may run from such a powerful being, but you can't hide. Eventually you will have to face Him, on his terms.

Most people throughout the ages have believed (and it is a distinct possibility) that such a Creator will judge us for our actions on this earth.  Therefore it makes sense to investigate and see if He has communicated with his creation. This means investigating religion.  Of course there are many religions in the world.  For the sake of your eternal destiny it is prudent to determine (based on the evidence) which religion is true.

The good news is, there are indisputable facts indicating He not only has communicated with us, but that He loves us, and has personally provided a means to bring forgiveness for our shortcomings.  Shortcomings that instinctively cause us to fear Him.

In light of these considerations Choose your response:

I guess I really do believe in God, I am willing to assume for now that the Bible may have possibly been left as a message from God.

I can believe there is possibly some sort of personal creator/God, but I don't think the Bible is really " a message from god"

I still don't believe in God- take me back to the reasons, and I'll pick another one.
