Are you saying the God of Christians is the same as the god of ego/satan?
Or two separate entities? (Correct)
There is only one God, and by living in a Christian-mayority country, I have never heard of any Christian that had the concept of God correctly. You try to put Him into a non-existing concept that is only existent in your brain.
Your brain can never understand God, but you can experience Him.
When you say that Christian´s God is different than the Hindu God, or the African tribe God, you are mistaken, you are judging. By doing that, you are going against the same principles you are standing for.
Just by the fact that you go to church, and pray. You are going to the church only for others to see you, that is a fact. You don´t go to the church because that is what is in your heart. You go to church because
you have been told that that is the right thing to do, and when you go, you see others and you don´t feel so alone.
But this is a desception, because as Jesus said, you should be with God in secret, alone, you don´t need others to tell you that what you are doing is right, you just feel it.
"Truly, they got what they deserve", only means that you got the respect of other Christians, no one, or nothing else...
God knows what you are thinking, then why pray???
Praying what is not in your head is hipocresy, and Jesus said it too.
I once saw a woman that was talking about how she hated two of her co-workers, and how she hated her boss, and she wished that they get punished for making her feel bad. So she prayed to God (she was a Christian, of course): "God make them receive what they deserve", hoping that by saying that, God will hear her and punish her co-workers for doing evil things.
And she is hoping to get a rewards from God, why for hating people? for asking God to punish others? what about herself, what she has done bad? is she to be free from punishment because she speaks to her imaginary friend?
