--------------
Yes, and the God of Christianity is also very different from the God of Christendom. He is the same God of Abraham , Isaac and Jacob, the same God that Jesus worshipped.

(Exodus 3:15) Then God said once more to Moses: “This is what you are to say to the Israelites, ‘Jehovah the God of your forefathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.’ This is my name forever, and this is how I am to be remembered from generation to generation.
