17:1 And when Abram was ninety nine years old - Full thirteen years after the birth of Ishmael. So long the promise of Isaac was deferred; Perhaps to correct Abram's over - hasty marrying of Hagar. That Abram and Sarai being so far striken in age, God's power in this matter might be the more magnified. The Lord appeared unto Abram - In some visible display of God's immediate glorious presence with him. And said, I am the Almighty God - By this name he chose to make himself known to Abram, rather than by his name Jehovah, Exo 6:3. He used it to Jacob, Gen 35:11. They called him by this name, Gen 28:5 43:14 48:3. It is the name of God that is mostly used throughout the book of Job, at least 30 times in the discourses of that book, in which Jehovah is used but once. After Moses, Jehovah is more frequently used, and this very rarely. I am El - Shaddai. It speaks the almighty power of God, either As an avenger, from wrv he destroyed, or laid waste; so some: and they think God took this title from the destruction of the old world: Or, As a benefactor, v for rva who, and yr it sufficeth. Our old English translation reads it here, very significantly, I am God All - sufficient. The God with whom we have to do, is self - sufficient; he hath every thing, and he needs not any thing. And he is enough to us, if we be in covenant with him; we have all in him, and we have enough in him; enough to satisfy our most enlarged desires; enough to supply the defect of every thing else, and to secure us happiness for our immortal souls. But the covenant is mutual, walk before me, and be thou perfect - That is, upright and sincere. Observe, That to walk before God, is to set God always before us, and to think, and speak, and act, in every thing as those that are always under his eye. It is to have a constant regard to his word, as our rule, and to his glory, as our end, in all our actions. It is to be inward with him in all the duties of religious worship, and to be entire for him in all holy conversation. That upright walking with God is the condition of our interest in his all - sufficiency. If we neglect him, or dissemble with him, we forfeit the benefit of our relation to him. A continual regard to God's all - sufficiency will have a great influence upon our upright walking with him.
17:1-6 The covenant was to be accomplished in due time. The promised Seed was Christ, and Christians in him. And all who are of faith are blessed with faithful Abram, being partakers of the same covenant blessings. In token of this covenant his name was changed from Abram, a high father, to Abraham, the father of a multitude. All that the Christian world enjoys, it is indebted for to Abraham and his Seed.
