There was a time after God delivered Israel from Egypt into the promised land when they were harassed by the nation of Midian for seven years. The people of Israel hid in mountain clefts, caves and strongholds. Every time they planted crops, marauders from Midian and other places would attack them. They would camp out, destroy the crops, steal the sheep, goats, cattle and donkeys and leave the land stripped bare. The people of Israel became impoverished, destitute and on the verge of starvation. They finally began to cry out to God for help.
I once watched a lecture from a well-known university. Although the subject had no direct connection with theology, the Professor decided to venture there anyway. He advocated that the god of the Old Testament was a god of Anger and Judgment and that the god of the New Testament is a god of Love and Mercy. I’m not certain where his information came from, but many modern Christians seem to agree with him.
