thank you for this post they are good questions we should ask to ourselves

1. What do I believe?
I believe in the power which created us, God.
and that i must be born for a reason and give something to this life.

2. Why do I believe this?
not only spiritual, but i feel God signs guiding me in certain things for a reason.
and believing that i got reason to be born make me continue living no matter what.

3. What does this belief do for me?
even if i still get depressed, have mental problems, God save me and i feel him assuring me everything will be fine, i did wish to die once by anyway but i felt something whisper to me that its not my time yet and something waiting for me.

4. What does this belief guarantee me?
better thing that will appear on right time
