You claim your hero was Martin Luther. So I suppose you are a Christian. Did you know that Christ's Father was "the Jewish God" ? You might want to have a talk with Jesus about you badmouthing His Father...
There is only one God and He never changes. More inclined to believe that it is mankind's understanding of the nature of God and how He inter-acts with his creature from generation to generation that changes. The God of yesterday's understanding is still valid for those who do not see His Advent[ure] into flesh.
For as it has been written, not one jot or tittle shall pass from the law until all be fulfilled. It is still valid for those who have not experienced the fulfillment or passed from belief into knowledge.
To paraphrase a great truth, 'greater is the law which is written on the fleshly tables of your heart than that which is written on paper. And "Greater is he within you than he who is in the world." (1 John 4:4)
So if the epitome of Christian thought is that God is within us, then to visualize God as an 'entity' somewhere 'up there' or unappoachable to us as individuals, then we are denying the reality of God and the existence of the true dwelling place of God.
The differences in the understanding or perception of God can be seen by how much one distances themselves from the presence of God. And the good news is that God can be as close as you want him to be.
So whether you are Muslim, Jew, or Christian, you can make your own judgements on what that distance is.
But be forewarned. The closer the light, the lesser the false ego with its attendant demands for self-glorification.
(Not trying to be preachy here, but when God is the topic, I would hope all views are acceptable for discourse as long as we are not in the religion forum.)
