Genesis 21
v1-8: God’s timing is perfect. His promises will be kept, not “at the time we set,” but “at the time he sets, which is the best time.” Not one word He has spoken “will fall to the ground, for he who has promised is faithful.”
v9-21: “There are many who are close to the children of God in this world and yet do not share with them in the inheritance as sons.” Those who are “born only physically, and are not born again,” will be “rejected and driven away from God.”
v22-34: It wasn’t just Abraham’s profession of faith that was public, so was his worship of God.
Genesis 22
v1-10: “The obedience of Abraham in offering up Isaac” pictures “the love of God to us, in delivering up his only-begotten Son to suffer and die for us, as a sacrifice.” Abraham said that God himself will provide a lamb for the burnt offering, and in Christ, “the great sacrifice of atonement, was provided by God.”
v11-14: “Christ was sacrificed in our place, as this ram instead of Isaac.”
v15-24: As Abraham is promised physical descendants who will have physical victories over their enemies, so through his promised offspring, Christ, he will have a “spiritual offspring” as “numerous as the stars of heaven,” that will have “spiritual victories” as “by their faith, overcome the world, and triumph over all the powers of darkness.”
Genesis 23
v1-2: “Even those who live the longest must die.” Though Abraham and Sarah had been together for many years, death parted them. “Death parts those whom nothing else can part.”
v3-20: Abraham longed “for a better country, that is, a heavenly one.” By ensuring that Sarah’s body is taking care of, he shows his belief and expectation that one day it will be raised. “Why should care be taken of the body if it is thrown away forever, and not to rise again?”
