God's promises to Abraham

In my first post I looked at Hebrews 6:13-19, which notices that God gave Abraham both a promise and an oath, so that he would be entirely sure that God would do what he said. But it has only occurred to me recently that one consequence of God giving multiple promises is that he would not necessarily have promised the same stuff each time. This is a new idea for me! I have always thought that each time God made a promise to Abraham he promised the same thing, but is that what the Bible actually shows? Obviously other people think the same, for whenever I have studied the promises God made to Abraham with others, we have never comprehensively looked at every time God made promises. (Sometimes God's covenant has been discussed without even reading when he gave it!) So I will briefly now look at God's promises to Abraham as recorded in Genesis, the plurality referring not to the objects of his promises, but to the times of giving. For simplicity's sake I will refer to Abram as Abraham, and I'll say Yahweh when יהוה is used.

12:1-3: In this the first, and in many ways stereotypical, occasion Yahweh promises many things to Abraham, which include: land, guidance, that his descendants will become a great nation, blessing, fame, reciprocal blessings/cursings, and to bless all other people of the earth through Abraham.

12:7: Yahweh promises to Abraham's descendants the land in which Abraham lives.

13:14-17: Yahweh promises to give the land which Abraham sees and walks through to his descendants forever. He promises to give Abraham as many descendants as there is dust on the earth. This passage shows that Yahweh truly did promise Abraham the physical land of Canaan, the one he had walked through kicking up dust, forever. Those who say it was only a temporary promise which would be replaced with the promise of heaven can't do this promise justice.

15:1-5: Yahweh promises Abraham a true son of his own blood. He promises to give Abraham as many descendants as there are stars. He also promises to reward Abraham greatly.

15:7-21: Yahweh makes (or 'cuts') his covenant with Abraham, promising to give to him and his descendants the land of Canaan, from the river of Egypt to the Euphrates: the lands of the Kenite, Kenizzite, Kadmonite, Hittite, Perizzite, Rephaim, Amorite, Canaanite, Girgashite and Jebusite. However before then his descendants will be enslaved in another land for four hundred years. But Yahweh will judge judge that nation and Abraham's descendants will raid their possessions as they are leave. He also says that he will give Abraham a good and long life.

17:1-21: Wow okay, this one is big. Yahweh again gives his covenant, and says he will give Abraham many descendants, so many in fact that they will form many nations and will even have kings! Yahweh's covenant to all of these people for all time is that Yahweh will be their God and that he will give them the land of Canaan as an 'everlasting possession.'

God then gives Abraham an instruction, as part of this covenant, that he and all his descendants must follow: they must circumcise all the males in the households, even those who are not descendants of Abraham. Anyone who is uncircumcised must be removed from God's people, as they have broken the covenant.

God then renames Sarah and says he will bless her and give her a son. She will be the mother of many nations and kings. God tells them to name their son Isaac and says he will inherit the covenant. Their son Ishmael, though he will not inherit the covenant, will still be greatly blessed and will be the father of a great nation and twelve princes.

18:10-14: Yahweh says he will return the next year and that Sarah will have a son.

21:12-13: God reminds Abraham that through Isaac will God keep his covenant, and that he will still make a nation of Ishmael's descendants.

22:15-18: Yahweh swears by his own name, as Hebrews quotes, that Abraham will have as many descendants as there are stars or grains of sand on the beach! His descendants will conquer their enemies. And because Abraham has obeyed Yahweh, all other nations will be blessed through Abraham's descendants.

And in 24:1 we have the lovely note that in Abraham's old age Yahweh had blessed him in every way.

From looking at these texts the situation is still quite complicated! God makes promises, cuts covenants and swears an oath by his name. He repeatedly promises to give Abraham many descendants and to give them the land he lives in. He makes those promises explicit, specifying the borders of the land and the only son he would continue his covenant with. But other promises are only given once, like that of a famous name and kingly descendants. I haven't looked at the contexts yet. Are there reasons why God repeats certain promises at certain times?

If nothing else we can say that Yahweh was entirely serious from the moment he first spoke to Abraham in Haran till Abraham's last day, one hundred years later. How great would it be to know God's faithfulness for such an immense time!

Modus operandi

Clearly, God’s promise to give the whole earth to Abraham and his descendants was based not on his obedience to God’s law, but on a right relationship with God that comes by faith. If God’s promise is only for those who obey the law, then faith is not necessary and the promise is pointless. For the law always brings punishment on those who try to obey it. (The only way to avoid breaking the law is to have no law to break!)

So the promise is received by faith. It is given as a free gift. And we are all certain to receive it, whether or not we live according to the law of Moses, if we have faith like Abraham’s. For Abraham is the father of all who believe. That is what the Scriptures mean when God told him, “I have made you the father of many nations.” This happened because Abraham believed in the God who brings the dead back to life and who creates new things out of nothing.

(Romans 4:13-17, NLT)

Paul writes here about two of the covenants, Abraham's and the Sinai, and his purpose is to show that God always works the same way. I like to say that God's modus operandi is grace.

God chose Abraham and made a covenant with him before Abraham did a thing. Even before God gave the rite of circumcision he considered Abraham righteous. What mattered was that Abraham trusted God to do all he promised. It was the same with the law of Moses, given as part of the Sinai covenant. All the law brings, says Paul, is punishment. The covenant's promised blessings are given freely to everyone who shares Abraham's faith.

God's MO is grace. He chooses to bless people just cause he feels like it. The only proper response is that we trust him to do just that. It's always been this way. And if it ever seems like someone earned God's favour then we must investigate more because that's also not how God works.

Covenant Theology is based on the concept of the Covenant of Grace. Although they mean much of the same, the use of covenant language is unhelpful and confusing. The Covenant of Grace is an ahistorical one, being made outside of time between God and the fuzzy group of all his people. I don't know if in the Ancient Near East's understanding that would be recognised as a covenant, but I suspect it would not. It's true that God always acts by grace, but I question what value there is in proposing an ahistorical "theological" covenant (ie, one not mentioned by the Bible explicitly.)
