I like your preposition on this. Therefor I am glad to give you my reasons for believing in God.
First of all, what most of the people here will say, including myself, is that I have a feeling that God exist. That feeling is not just a reason for belief. It is the belief itself!
I have lost my belief many times, but I've allways felt a need to believe, and I've prayed God to let me believe.
The belief can't be constructed logically, thus I can't make you believe, no matter what I do (with one exception) - and therefor also my need to pray to God (though I would lie if I said that I didn't try to "construct" my belief to it's former self. I got far on that way, but the feeling I got never came close to the feeling of belief, though I did get some insights - but these were not made by me either - though I must admit, that I sometimes said they were and even *SHAME* lied about the way I came to the conclusion and thus hopelessly getting on the wrong path - the temptation was too great, since I clearly saw how I could have arrived to the same conclusion as the insight I got).
It's very sad when one looses her/his belief. Cause I know how desperatly we need it. Though many here will say we don't need it that much. But I felt so lost when I lost my belief, belief is a guidance, I still feel a emptiness inside. No "logic" could fill that hole. Cause I knew what I had. Thus had the full understanding of what I had lost. Allthough the understanding was replaced with emptiness. You only remember what you still have.
If I just become nothing when I die, then it would be so sad, cause then I loose EVERYTHING, even the thought that there is a world. That there is a reality. That there is something instead of nothing.
Ok, I guess it doesn't matter when I'm dead. But it matters now - and I don't want it to be so. When I hear other talk about death and that it isn't so bad to become nothing, then I feel that they don't see the full consequence of what they are saying. We should cry when we say that. Cause it is the end of time, truly the end of it all.
But.
I am aware. I am aware of my time here and now. The thing is, I don't feel that I would be aware here and now if I weren't aware after death. Cause if everything ends after death, then too ends the past me and the future me.
I realise that there are much anxiety in my post. But that's because there should be. Death isn't a easy subject and if I didn't express my anxiety for death, then I wouldn't be true to me nor you.
If the truth is, that I end with death then please don't tell me. If the belief of God is only because we would have the strength to live, then that too is mercy.
