When Moses stood in the breach for the people, I notice he implored the Lord based on His promises and His reputation.
What do you notice?
“O Lord!” he said. “Why are you so angry with your own people whom you brought from the land of Egypt with such great power and such a strong hand? Why let the Egyptians say, ‘Their God rescued them with the evil intention of slaughtering them in the mountains and wiping them from the face of the earth’?
Turn away from your fierce anger. Change your mind about this terrible disaster you have threatened against your people! Remember your servants Abraham, Isaac, and Jacob. You bound yourself with an oath to them, saying, ‘I will make your descendants as numerous as the starts of haven. And I will give them all the land that I have promised to your descendants, and they will possess it forever.'”
So the Lord changed his mind about the terrible disaster he had threatened to bring on his people (Exodus 32:11-14).”
