intense quakes on the feeling of truth

Assume,

God, who is omnipotent and omniscient, created everything from nothingness. He created humans in such a way that they need to believe, and in order to satisfy this need, they created artificial religions. God’s final purpose is to judge people according to what they believe in. If a person believes in these artificial religions (all religions are this kind, in this assumption) dogmatically, rejects scientific progress, avoids philosophical thought, he goes to hell. If he does not do these, then he goes to heaven.

So, if you philosophically deduced that God must exist, and after that thought about which God to believe in, then chose a God to believe from an available religion, you are on the wrong way, because this model of God has the same probability to be real as any other God. If you think that God exists, and believe in, say, Christian God (maybe to avoid any possible punishment), and this rationalist God happens to be the real God, then you are doomed for eternity. If you believe in this rationalist God, and Christian God happens to be the real God, then you are doomed for eternity again.

The important thing is, after the philosophical deduction of God’s existence, you should not jump into conclusions too quickly (or at all).
