v1: After this comes the Lord's word to Abram;
- do not be afraid; perhaps he has been fighting with doubts and fears;
- the shield is the Lord; He has protected Abram, and will continue to do so;
- very great reward; as in Genesis 14.19, contrast 14:22-24; the Lord Himself, Proverbs 2:4; Romans 11:32; Abram has turned down material reward from the king of Sodom, and so the Lord Himself is his reward.
v2-3: Abram's problem;
- no offspring to inherit his blessings;
- not a question of unbelief, rather an indication of Abram's intimacy with God;
- he asks the Lord to deal with the issue, Luke 1:37.
v4: God's specific promise; a son from your own body.
v5: A further and greater promise; a spiritual, heavenly people, numerous descendants.
'The stars were designed by the creator to be a type of the saints, the spiritual seed of Abraham. And the seeming multitude of them, which is much greater than the real multitude of visible stars, was designed as a type of the multitude of the saints.' (Jonathan Edwards, The Blank Bible, quoted in Rejoice and Tremble, by Michael Reeves.)
v6 : Abram's response; he believes God. The Lord accounted his faith as righteousness; no need of works or sacrifice to gain the righteousness of God.
In Romans 4:18-22, Paul teaches us that;
Abram's faith was contrary to hope;
- he was as good as dead, for he was so old;
- Sarah's womb was barren.
These things were all impossible, but Abram still believes. He simply accepts what God says. God is utterly faithful to His word, and we response in faith to Him.
v7: A reminder of God's call, bringing Abram from Ur to possess the land of Canaan.
v8: Abram looks to the Lord to confirm this promise also.
v9-10: A demonstration of covenant/contract/agreement; normally both parties would pass between the pieces of the animals, ie: to pronounce a curse upon either who break the covenant. But here only the Lord, in the burning torch (v17, see John 5:35) passes through, indicating that the covenant is entirely His responsibility. See Jeremiah 34:17-19.
v11: Protecting the covenant; the vultures come down to eat the dead meat. Abram has to wait hours before the confirmation from the Lord.
v12-16: A set of promises in Abram's vision;
- the family from Abram will be slaves in Egypt for 400 years;
- they will come out with great possessions;
- God will judge Egypt;
- Abram himself will die at peace;
- later his descendants will return to this land.
The details are staggering in their accuracy, and indicate God's power and faithfulness. We see too God's dealing with nations; with Israel, Egypt, and the Amorites.
v17: The smoking brazier (or torch), indicating God's presence, and His promise to honour His own words.
v18-21: The extent of the promised inheritance. This is God's word, His covenant. The true Christian can rely on just what He says.
