The God of the OT was a vengeful God, merciful only when the isrealites were worshipping him excactly as he dictated.
While I guess a God would have the right to dictate how he wants to be worshipped, seems kind of childish...I want a toy right now!! I cant have it?? Well then I am throwing myself on the ground, holding my breath till I turn blue, and then Im gonna kick and scream and break all your stuff until you give me what I want!!!
I know, I know, the paralell isnt accurate, but if you think about it, He punished the isrealites ALOT. and killed millions of pagans (including women and children) simply because they werent worshipping him. (granted many were bad, but how can children be bad?)
Jesus is the OPPOSITE of the OT God. well in my viewpoint of him anyway. Jesus to me was forgiving, prefered to be in the company of sinners, than with the self-rightous pharisees, and loved children. He LOVED people. He wanted to teach them, even tho he was hungry and tired, he wouls spend hours with them, and even feed them. Yes he got angry at the money changers in the temple, chasing them out and whipping them with ropes..lol, but it was because they were taking advantage of the people, whom he cared about.
that's my viewpoint anyway...
