God encourages Abram. (1) The Divine promise, Abraham is justified by faith. (2-6) God promises Canaan to Abraham for an inheritance. (7-11) The promise confirmed in a vision. (12-16) The promise confirmed by a sign. (17-21)
Verse 1 God assured Abram of safety and happiness; that he should for ever be safe. I am thy shield; or, I am a shield to thee, present with thee, actually caring for thee. The consideration that God himself is, and will be a shield to his people, to secure them from all evils, a shield ready to them, and a shield round about them, should silence all perplexing, tormenting fears.
Verses 2-6 Though we must never complain of God, yet we have leave to complain to him; and to state all our grievances. It is ease to a burdened spirit, to open its case to a faithful and compassionate friend. Abram's complaint is, that he had no child; that he was never likely to have any; that the want of a son was so great a trouble to him, that it took away all his comfort. If we suppose that Abram looked no further than outward comfort, this complaint was to be blamed. But if we suppose that Abram herein had reference to the promised Seed, his desire was very commendable. Till we have evidence of our interest in Christ, we should not rest satisfied; what will all avail me, if I go Christless? If we continue instant in prayer, yet pray with humble submission to the Divine will, we shall not seek in vain. God gave Abram an express promise of a son. Christians may believe in God with respect to the common concerns of this life; but the faith by which they are justified, always has respect to the person and work of Christ. Abram believed in God as promising Christ; they believe in him as having raised him from the dead, ( Romans 4:24 ) . Through faith in his blood they obtain forgiveness of sins.
Verses 7-11 Assurance was given to Abram of the land of Canaan for an inheritance. God never promises more than he is able to perform, as men often do. Abram did as God commanded him. He divided the beasts in the midst, according to the ceremony used in confirming covenants, ( jeremiah 34:18 jeremiah 34:19 ) . Having prepared according to God's appointment, he set himself to wait for the sign God might give him. A watch must be kept upon our spiritual sacrifices. When vain thoughts, like these fowls, come down upon our sacrifices, we must drive them away, and seek to attend on God without distraction.
Verses 12-16 A deep sleep fell upon Abram; with this sleep a horror of great darkness fell upon him: a sudden change. The children of light do not always walk in the light. Several things were then foretold. 1. The suffering state of Abram's seed for a long time. They shall be strangers. The heirs of heaven are strangers on earth. They shall be servants; but Canaanites serve under a curse, the Hebrews under a blessing. They shall be suffers. Those that are blessed and beloved of God, are often sorely afflicted by wicked men. 2. The judgment of the enemies of Abram's seed. Though God may allow persecutors and oppressors to trample upon his people a great while, he will certainly reckon with them at last. 3. That great event, the deliverance of Abram's seed out of Egypt, is here foretold. 4. Their happy settlement in Canaan. They shall come hither again. The measure of sin fills gradually. Some people's measure of sin fills slowly. The knowledge of future events would seldom add to our comfort. In the most favoured families, and most happy lives, there are so many afflictions, that it is merciful in God to conceal what will befall us and ours.
Verses 17-21 The smoking furnace and the burning lamp, probably represented the Israelites' severe trials and joyful deliverance, with their gracious supports in the mean time. It is probable that this furnace and lamp, which passed between the pieces, burned and consumed them, and so completed the sacrifice, and testified God's acceptance of it. So it intimates that God's covenants with man are made by sacrifice, ( Psalms 50:5 ) . And we may know that he accepts our sacrifices, if he kindles in our souls pious and devout affections. The bounds of the land granted are stated. Several nations, or tribes, are spoken of, that must be cast out to make room for the seed of Abram. In this chapter we perceive in Abram faith struggling against, and triumphing over, unbelief. Wonder not, believers, if you meet with seasons of darkness and distress. But it is not the will of God that you should be cast down: fear not; for all that he was to Abram he will be to you.
Genesis 15:1-21 . DIVINE ENCOURAGEMENT.
1. After these things--the conquest of the invading kings.
the word of the Lord--a phrase used, when connected with a vision, to denote a prophetic message.
Fear not, Abram--When the excitement of the enterprise was over, he had become a prey to despondency and terror at the probable revenge that might be meditated against him. To dispel his fear, he was favored with this gracious announcement. Having such a promise, how well did it become him (and all God's people who have the same promise) to dismiss fears, and cast all burdens on the Lord ( Psalms 27:3 ).
2. Lord God, what wilt thou give?--To his mind the declaration, "I am thy exceeding great reward" [ Genesis 15:1 ], had but one meaning, or was viewed but in one particular light, as bearing on the fulfilment of the promise, and he was still experiencing the sickness of hope deferred.
3. Eliezer of Damascus . . . one born in my house is mine heir--According to the usage of nomadic tribes, his chief confidential servant, would be heir to his possessions and honors. But this man could have become his son only by adoption; and how sadly would that have come short of the parental hopes he had been encouraged to entertain! His language betrayed a latent spirit of fretfulness or perhaps a temporary failure in the very virtue for which he is so renowned--and absolute submission to God's time, as well as way, of accomplishing His promise.
4. This shall not be thine heir--To the first part of his address no reply was given; but having renewed it in a spirit of more becoming submission, "whereby shall I know that I shall inherit it" [ Genesis 15:8 ], he was delighted by a most explicit promise of Canaan, which was immediately confirmed by a remarkable ceremony.
9-21. Take me an heifer, &c.--On occasions of great importance, when two or more parties join in a compact, they either observe precisely the same rites as Abram did, or, where they do not, they invoke the lamp as their witness. According to these ideas, which have been from time immemorial engraven on the minds of Eastern people, the Lord Himself condescended to enter into covenant with Abram. The patriarch did not pass between the sacrifice and the reason was that in this transaction he was bound to nothing. He asked a sign, and God was pleased to give him a sign, by which, according to Eastern ideas, He bound Himself. In like manner God has entered into covenant with us; and in the glory of the only-begotten Son, who passed through between God and us, all who believe have, like Abram, a sign or pledge in the gift of the Spirit, whereby they may know that they shall inherit the heavenly Canaan.
