The fifteenth chapter of Genesis contains the first account of the covenant made with Abraham. “The word of the Lord came unto Abram in a vision, saying, Fear not Abram; I am thy shield, and thy exceeding great reward.” Notice the statement that God said that He Himself was Abraham’s reward. If we are Christ’s, then we are Abraham’s seed, and heirs according to the promise. Heirs of what? — “Heirs of God, and joint-heirs with Christ.” Rom. 8:17. The same inheritance is mentioned by the Psalmist: “The Lord is the portion of mine inheritance.” Ps. 16:5. So here again we have a link to connect all God’s people with Abraham. Their hope is nothing else but the promise of God to him.
Everywhere Abraham went, he built an altar to the Lord. As you read this, remember that the promise that all nations should be blessed in Abraham, specified even families. The religion of Abraham was a family religion. The family altar was never neglected in his household. This is not an empty figure of speech, but comes from the practice of the fathers to whom the promise was made, and of which we are partakers if we are of their faith and practice. An Example for Parents: God said of Abraham, “For I have known him, in order that he may command his children and his household after him, that they keep the way of the Lord, to do righteousness and justice, that the Lord may bring to Abraham what He has spoken to him” (Gen. 18:19).
