Better terminology for "Father and Son" ?

[Wyrd of Gawd]

And why didn't Jesus know why God had forsaken Him on the cross ???

Godboy shudda been able to noodle that one out with both hands tied behind his back, let alone nailed to a board.

Assuming that the Yeshua guy was an actual person and not an imaginary one it's easy to see how he had been brainwashed all of his life into thinking that he was really Yahweh's son.  His mother had been feeding him a line of BS about it since he was a minute old and the local yokels thought that he was special.  So after years and years of such BS he was convinced that he was the real deal.  Then, when he had gotten nailed he finally realized that the joke was on him.  He was just a deluded lunatic.
