In Deuteronomy 30:1-10 Moses speaks fo the days when God will circumcise the hearts of his people. The fact that this is necessary shows that without God first circumcising the heart, no one can believe. Deuteronomy 30:1-10 shows that the entire Bible is one great story of God’s sovereign grace. Everything that we have, even faith, is a gift of God. May God be praised for his marvelous mercy to men.
