Israel has expressed some fruit of repentance of their idolatry, and Moses returns to plead with God to show grace toward His people. God announces to Moses His intention to be gracious and fulfill all His previous covenant promises to Israel because Moses has found favor with God and God will treat Israel as Moses deserves rather than as Israel deserves. Here we are clearly prepared for the work of Christ and come to understand it is not our repentance that saves us or makes us right with God, but God's pleasure in His Son.
