If God is all-powerful, why does he require that we believe in him?

Because he has a worse ego problem than I do.

The belief I have in God is called trust.

My spiritual life depends on HIM alone. We trust God and we follow and obey and love him.

An unbeliever responds normally and rationally to some one he does not know or believe in someone he did not trust.

The kind of trust God desires is the same one he sees a parent have with their own children that they love. A child will respond to his parents because of trust. This belief.

It's that simple and nothing more.

A father is 'all-powerful' over his children (for a time). Does that father want the best for his kids? Including loving him and following his teaching so they have a full and beneficial life? (Both of which are the real meaning of the word 'believe').

Its not that hard of a concept to grasp.

God does not require that you believe in him, the Church requires that you believe what they tell you.

If you had the chance to create something, wouldn't YOU expect it to love and worship you? Are you seriously telling me you wouldn't throw them to eternal hellfire if they didn't kiss your ***? Uh

Because even if you are all powerful you can still be a vain vindictive ******

This is why religion is about money in the first place.

He must be self-conscious

He doesn't require it, He allows you to choose it.
