You believe in things you do not know.
Your belief says you wish things were
like you want them to be.
If sun shines you never say that
you believe the sun is shining.
What is there to believe if
it has become your experience?

Do you know why you believe in GOD?

Do not be proud if you believe in GOD being present.
It is the same if you believe in his absence.

In both cases you have missed HIM.
