Here is, I. The time when God made Abram this gracious visit: When he was ninety-nine years old, full thirteen years after the birth of Ishmael. 1. So long, it should seem, God's extraordinary appearances to Abram were intermitted; and all the communion he had with God was only in the usual was of ordinances and providences. Note, There are some special comforts which are not the daily bread, no, not of the best saints, but they are favoured with them now and then. On this side heaven they have convenient food, but not a continual feast. 2. So long the promise of Isaac was deferred. (1.) Perhaps to correct Abram's over-hasty marrying of Hagar. Note, The comforts we sinfully anticipate are justly delayed. (2.) That Abram and Sarai being so far stricken in age God's power, in this matter, might be the more magnified, and their faith the more tried. See Deu 32:36; Joh 11:6, Joh 11:15. (3.) That a child so long waited for might be an Isaac, a son indeed, Isa 54:1.

II.The way in which God made this covenant with him: The Lord appeared to Abram, in the shechinah, some visible display of God's immediate glorious presence with him. Note, God first makes himself known to us, and gives us a sight of him by faith, and then takes us into his covenant.

III.The posture Abram put himself into upon this occasion: He fell on his face while God talked with him, Gen 17:3. 1. As one overcome by the brightness of the divine glory, and unable to bear the sight of it, though he had seen it several times before. Daniel and John did likewise, though they were also acquainted with the visions of the Almighty, Dan 8:17; Dan 10:9, Dan 10:15; Rev 1:17. Or, 2. As one ashamed of himself, and blushing to think of the honours done to one so unworthy. He looks upon himself with humility, and upon God with reverence, and, in token of both, falls on his face, putting himself into a posture of adoration. Note, (1.) God graciously condescends to talk with those whom he takes into covenant and communion with himself. He talks with them by his word, Pro 6:22. He talks with them by his Spirit, Joh 14:26. This honour have all his saints. (2.) Those that are admitted into fellowship with God are, and must be, very humble and very reverent in their approaches to him. If we say we have fellowship with him, and the familiarity breeds contempt, we deceive ourselves. (3.) Those that would receive comfort from God must set themselves to give glory to God and to worship at his footstool.

IV.The general scope and summary of the covenant laid down as the foundation on which all the rest was built; it is no other than the covenant of grace still made with all believers in Jesus Christ, Gen 17:1. Observe here,

1.What we may expect to find God to us: 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 28:3; Gen 43:14; Gen 48:3. It is the name of God that is mostly used throughout the book of Job, at least in the discourses of that book. After Moses, Jehovah is more frequently used, and this, El-shaddai, very rarely; it bespeaks the almighty power of God, either, (1.) As an avenger, from shôdeh he laid waste, so some; and they think God took this title from the destruction of the old world. This is countenanced by Isa 13:6, and Joe 1:15. Or, (2.) As a benefactor shin for 'ăsher who, and day sufficient. He is a God that is enough; or, as our old English translation reads it here very significantly, I am God all-sufficient. Note, The God with whom we have to do is a God that is enough. [1.] He is enough in himself; he is self-sufficient; he has every thing, and he needs not any thing. [2.] 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 to us a happiness for our immortal souls. See Psa 16:5, Psa 16:6; Psa 73:25.

2.What God requires that we should be to him. The covenant is mutual: Walk before me, and be thou perfect, that is, upright and sincere; for herein the covenant of grace is well-ordered that sincerity is our gospel perfection. Observe, (1.) That to be religious is to walk before God in our integrity; it 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, and to be continually in his fear. It is to be inward with him, in all the duties of religious worship, for in them particularly we walk before God (Sa1 2:30), and to be entire for him, in all holy conversation. I know no religion but sincerity. (2.) 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 and comfort of our relation to him. (3.) A continual regard to God's all-sufficiency will have a great influence upon our upright walking with him.

The Lord appeared to Abram - See note on Gen 15:1.

I am the Almighty God - אני אל שדי ani El shaddai, I am God all-sufficient; from שדה shadah, to shed, to pour out. I am that God who pours out blessings, who gives them richly, abundantly, continually.

Walk before me - התהלך לפני hithhallech lephanai, set thyself to walk - be firmly purposed, thoroughly determined to obey, before me; for my eye is ever on thee, therefore ever consider that God seeth thee. Who can imagine a stronger incitement to conscientious, persevering obedience?

Be thou perfect - והיה תמים vehyeh thamim, and thou shalt be perfections, i.e., a together perfect. Be just such as the holy God would have thee to be, as the almighty God can make thee and live as the all-sufficient God shall support thee; for he alone who makes the soul holy can preserve it in holiness. Our blessed Lord appears to have had these words pointedly in view, Mat 5:48 : Εσεσθε ὑμεις τελειοι, ὡσπερ ὁ Πατηρ ὑμων ὁ εν τοις ουρανοις τελειος εστι· Ye Shall Be perfect, as your Father who is in heaven is perfect. But what does this imply? Why, to be saved from all the power, the guilt, and the contamination of sin. This is only the negative part of salvation, but it has also a positive part; to be made perfect - to be perfect as our Father who is in heaven is perfect, to be filled with the fullness of God, to have Christ dwelling continually in the heart by faith, and to be rooted and grounded in love. This is the state in which man was created, for he was made in the image and likeness of God. This is the state from which man fell, for he broke the command of God. And this is the state into which every human soul must be raised, who would dwell with God in glory; for Christ was incarnated and died to put away sin by the sacrifice of himself. What a glorious privilege! And who can doubt the possibility of its attainment, who believes in the omnipotent love of God, the infinite merit of the blood of atonement, and the all-pervading and all-purifying energy of the Holy Ghost? How many miserable souls employ that time to dispute and cavil against the possibility of being saved from their sins, which they should devote to praying and believing that they might be saved out of the hands of their enemies! But some may say, "You overstrain the meaning of the term; it signifies only, be sincere; for as perfect obedience is impossible, God accepts of sincere obedience." If by sincerity the objection means good desires, and generally good purposes, with an impure heart and spotted life, then I assert that no such thing is implied in the text, nor in the original word; but if the word sincerity be taken in its proper and literal sense, I have no objection to it. Sincere is compounded of sine cera, "without wax;" and, applied to moral subjects, is a metaphor taken from clarified honey, from which every atom of the comb or wax is separated. Then let it be proclaimed from heaven, Walk before me, and be Sincere! purge out the old leaven, that ye may be a new lump unto God; and thus ye shall be perfect, as your Father who is in heaven is perfect. This is sincerity. Reader, remember that the blood of Christ cleanseth from all sin. Ten thousand quibbles on insulated texts can never lessen, much less destroy, the merit and efficacy of the great Atonement.

And when Abram was ninety years old and nine,.... Which was thirteen years after the birth of Ishmael last mentioned; so many years more it was before be is expressly told he should have a son by Sarai, or had the promise of Isaac, which was for the trial of his faith; and his age is here observed, that the power of God might be more manifest in fulfilling his promise, and giving him a son by Sarai:

the Lord appeared to Abram; in a visible manner, in an human form very probably, even the Logos, the Word and Son of God: it seems as if the Lord had not appeared to him since the birth of Ishmael, until this time; and if so, it may be thought to be a correction of him for listening to the voice of his wife in marrying Hagar, without asking counsel of God:

and said unto him, I am the Almighty God; as the Word of God is, as appears by his creation of all things, his in sustaining of them, his government of the church, his redemption of it, and preservation of his people safe to glory, see Rev 1:8; and this epithet is very appropriate here, when the Lord was about to give out a promise of a son to Abram and Sarai, so much stricken in years. Some render it "all sufficient" (c), as Jehovah is, sufficient in and of himself, and for himself, and stands in no need of any, or of anything from another; and has a sufficiency for others, both in a way of providence and grace:

walk before me: not as though Abram had not so walked, or had discontinued his walk before God, but that he would go on to walk by faith in a dependence on him for everything he wanted, both with respect to things temporal and spiritual; and to walk in all his commandments and ordinances, that he either had given, or should give him; and all this as in his presence, and under his watchful eye, that sees and observes all things, and before whom all things are naked and open, as all are to the essential Word of God, Heb 4:12,

and be thou perfect: upright and sincere in acts of faith, and in duties of religion, and go on to perfection; which though a sinless one is not attainable in this life, is desirable, and is to be had in Christ, though not in ourselves: but here it chiefly denotes an holy and unblamable life and conversation, which though not entirely free from sin, yet without any notorious ones, which bring dishonour to God, and disgrace upon a man's character and profession, see Gen 6:9. This respects not perfection in his body or flesh, as the Targum of Jonathan paraphrases it, through circumcision, by which the Jews (d) fancy Abram became perfect, but was not till circumcised.
