God is always faithful? God drowned all the earth's inhabitants during the days of Noah. I assume all those little children and babies, many still in the womb, must have been evil.
God ordered Joshua to murder everyone in Jericho and commanded Saul to kill every living Amalekite! Check out that odd little story in II Kings 2:23-25. Some kids tease Elisha because of his bald head. Elisha brings down the curse of God on them, two bears attacked and maul 42 of those wicked, wicked young ones.
Give me a break! How are such stories of violence and injustice evidence that God is always faithful. Well, yes, I also believe that God is always faithful, which is why I have to reject such tales of God-ordered bloody murder, revenge and wholesale slaughter in the Old Testament.
By the way, check out Ex. 21-22, Lev. 20, Deut. 22-23 and see how many of those laws suggest that God is reasonable, let alone faithful. What about the commandment to kill 'witches' or the one calling for the execution anyone who doesn't worship Jehovah? What about bringing a rebellious son to the village gate and having the elders stone him to death? I believe a father was even permitted to sell his daughter into slavery!
These images of God are far from the God of love which Christ revealed. When the woman was about to be stoned for adultery, what did he do?
