God isn't what you want him to be. It's not up to you to decide what he is or if he exists.
And I think any faith should not be taken at face value, or blindly followed. The nice thing about the Trinity is the Holy Spirit. You have to be open to it, and you have to accept it. The Holy Spirit is what directs you, not God. Some call it a conscience.
Sure it is.
No one has ever seen God, no one has ever spoken with God. Some people decided he looked like so old dude. I've decided God doesn't exist, or if he does, he's me.
I did that. It's done. You can't change that.
You decide he does exist, you decide he is a he. That's the human brain doing that, not some knowledge of something outside of humanity.
Look at Christianity. People have decided so well on what is Christianity that there are THREE main forms of it, Orthodox, Catholicism and Protestantism which might as well be call Pick-n'-Mix-ism.
Then within each of these people can't even decide on what the reality is.
