To be honest I think the God of the Old Testament and the God of the New Testament are not the same. NT God has rules but is love personified, and sacrificed His own Son to save His creation. OT God is Jewish to the core and largely concerned with women's menses, pigs and pork, smelling fresh lamb hot on the stone grill and sending Jews out to kill rival tribes, then laughing at them after he trolls them. That God never mentions Jesus once. Instead, it seems focused enormously on Jews.

To me the real God is the New Testament one and the Old Testament one is that little tribe's "god"... THE DEVIL
