This question is inspired by this: Did God REALLY want to destroy the people of Israel?
God says to Moses:
The Lord said to Moses, “I have seen this people, and behold, they are an obstinate people.
“Now then let Me alone, that My anger may burn against them and that I may destroy them; and I will make of you a great nation.”
But Moses pleads with the Lord:
Then Moses entreated the Lord his God, and said, “O Lord, why does Your anger burn against Your people whom You have brought out from the land of Egypt with great power and with a mighty hand?
“Why should the Egyptians speak, saying, ‘With evil intent He brought them out to kill them in the mountains and to destroy them from the face of the earth’? Turn from Your burning anger and change Your mind about doing harm to Your people.
Finally God changes his minds due to Moses's pleading:
"...the Lord changed His mind..."
My question is: Why does Moses who is a mere mortal have compassion for the people of Israel while God, who is of infinite goodness lacks it?
