“Your name will no longer be Abram, but your name will be Abraham; for I have made you a father of many nations” (Genesis 17:5). Each signals a pivotal redemptive-historical turn. Abram’s case inaugurates the line through which Messiah comes (Matthew 1:1). Theological Implications 1. Election: God selects a pagan from Ur (Joshua 24:2) and redefines him. 2. Universality: “Many nations” anticipates Gentile inclusion (Romans 4:11-17; Galatians 3:8). 3. Irrevocability: The covenant is “everlasting” (Genesis 17:7); Paul calls the gifts and calling of God “irrevocable” (Romans 11:29).
