Believing

There are things I believe.
There are things I want to believe.
There are things I used to believe and
things I simply cannot believe.
There are things I'm pretty sure I believe
but things happen which make me wonder.
There are things I believe with my head
but not with my heart,
and visa versa.
There are things I talk myself into believing.
Or out of.
And there's a world of things that other people believe.
What does God believe?
