What does it mean that the gifts and calling of God are without repentance?

Les explains that the word repentance is often misunderstood. Here it is not falling down on your face and weeping in sorrow for sin; it is a change of mind, a change of thinking. When applied to God's dealing with Israel, the question is whether He has changed His mind. The answer is no. So the verse means God's gifts and calling are without His changing His mind. Les connects this to God's ongoing love for the patriarchs—Abraham, Isaac, Jacob, Moses—and says the election, the remnant of Israel, is beloved because of their forefathers. God goes back to those patriarchs and His love for them when dealing with their offspring, and He is still preparing that remnant for the end-time events. Les then points back to Genesis 12 as the foundational promise behind this.
