It is hard to know how to approach this post; there is a bewildering amount of information on Abraham to be found in both Old and New Testaments. Also, the Abrahamic Covenant is the most controversial of all the covenants, having been very much tied in with the question of baptism. Now it goes without saying that Abraham was not himself baptized, nor did he ever baptize anyone, but nonetheless, paedobaptists argue that since male infants were circumcised in ancient Israel, the infant children of Christians ought to be baptized. In my opinion it is an error to start looking at a New Testament ordinance in the Old Testament; we should start with Christ, the Author and Perfecter of our faith (Heb 12:2). Here we shall consider the Abrahamic Covenant as a whole, but I hope to touch upon the question later.
The covenant with Abraham is revealed to us in four stages:-
Gen 12:1-3. The covenant Announced. The word ‘covenant’ is not mentioned here but Peter in Acts 3:25 makes it clear that God’s initial promises to Abram were part of the covenant. The three part of the covenant, Land, Nation, Seed are made clear.
Gen 15. The Covenant Transacted. The word ‘covenant’ is used in connection with Abraham for the first time, and a sacrifice is made. It is important to note that circumcision is not part of the covenant at this stage. The blessings promised to Abram are on the basis of his faith alone.
Gen 17. The Covenant Instituted. He receives a new name, and the sign of the covenant, circumcision,
Gen 23. The Covenant Confirmed. Abraham’s faith is proved by his actions (cf. Heb 11:17) and the promises repeated.
The Abrahamic Covenant, like the covenants with Noah and David, is a ‘covenant of promise’ (Ephesians 2:12). The word ‘promise’ is used very frequently in the New Testament with reference to Abraham (Acts 7:5; Rom 4:12; 9:4-9; Gal 3:5-29; 4:28; Heb 6:13-20; 11:9, 13, 17). The promises are ‘in Christ’ (Gal 3:17; cf. 2Cor 1:20) as well as ‘of Christ’ (Gal 3:16); that is, they refer to Christ and are for those who are His by faith. The ‘Seed of the woman,’ spoken of in Gen 3:15, is shown to be also the Seed of Abraham, but the blessing is to the whole world. The promises are entirely gracious. There was nothing in Abraham to make him worthy of being the recipient of these promises. He was not brought up in a household that worshipped Yahveh; ‘Your fathers, including Terah, the father of Abraham and the father of Nahor, dwelt on the other side of the river in old times: and they served other gods’ (Joshua 24:2-3). It was not the piety of Abraham which commended him to God, but grace alone through God’s sovereign election. Nor could Abraham do anything to bring the promises about; he and Sarah might have been married for about fifty years before ever God spoke to him (cf. Gen 12:4), and they were doubtless already resigned to childlessness, but God was pleased to show him unmerited favour.
With whom was the Abrahamic Covenant made? Only with Abraham, Isaac and Jacob. These last two received the Abrahamic promises not through their relationship to Abraham, but directly from God (Genesis 26:2-5; 28:12-15). The covenant is made with no one else. If I believe that God is going to make a great nation out of me, or make me a blessing to all nations, or give my descendants the Land of Canaan as a possession, I am more than likely to be deceiving myself. Nor could an Israelite appropriate the promises to himself; any of Abraham’s descendants other than Isaac and Jacob might be childless. But when we place our faith in the promised Seed, we may appropriate the promised blessing as we become a child of Abraham by faith (Galatians 3:7) and inherit the heavenly country that Abraham sought and found (Hebrews 11:15-16). The covenant ‘with Abraham, Isaac and Jacob’ is repeatedly mentioned in Scripture (Exodus 2:24; 32:13; Lev 26:42; Num 32:11; 2Kings 13:23; 1Chron 16:16ff; Psalms 105:9 etc.) but no one else is ever spoken of as being in the covenant with them.
We have said that the covenant promises to Abraham were of land, nation and seed. Each of these has both an earthly and a heavenly fulfilment. There is an earthly land of Canaan which the Israelites eventually came to inherit, but we are told in Romans 4:13 that the promise was for the whole world (cf. Matt 5:5; Rev 5:10), and in Hebrews 11:16 that Abraham looked forward to a heavenly city. These are fundamentally the same promise and refer to the new heavens and new earth and also to the heavenly Jerusalem of Rev 21;1-3 which Abraham will inherit along with all believers at the end of time. Likewise, there was an earthly nation descended from Abraham who came to live in Canaan, but we learn from Galatians 3:7 that believers of all nations are his true descendants and it is they who will inherit the heavenly promises.
This brings us nicely on to the two seeds of Abraham; for there are two seeds with two different promises. Firstly, there is a physical seed to whom are given physical promises- a great nation and a physical land for it to dwell in. These promises were received by Israel in full (Josh 21:43-45). This seed ‘after the flesh’ (Gal 4:29) is represented by Ishmael. It is most important to understand that Ishmael is not in the Covenant. ‘And Abraham said to God, “Oh, that Ishmael might live before you!” Then God said, “No, Sarah your wife shall bear you a son and you shall call his name Isaac. I will establish My covenant with him”’ (Gen 17:18-19). Nothing could be clearer than this; Ishmael is not in the covenant, although he receives the covenant sign (v26). Ishmael, though not an Israelite, is a type of Israel after the flesh. He receives the earthly promises (Genesis 17:20) and the outward sign, but not the spiritual blessings (Gal 4:30; Acts 7:51-53). He persecutes the True Seed (Gen 21:9; John 8:37ff; Gal 4:29). His circumcision is of no avail to him since he lacks what circumcision symbolized; a humble, circumcised heart (Jeremiah 9:25-26).
There is also a spiritual seed of Abraham; those who are in Christ, the True Seed, by faith. These are they who are looking for a heavenly country just as Abraham was. Just as Abraham did not receive an earthly inheritance in his lifetime (Acts 7:5 etc), so the true Israelite knew that Canaan was not his true home (Psalms 119:19. cf. 1Peter 2:11). He put no confidence in his circumcision, but rather his circumcision spoke to him of the promised Seed of Abraham who should come (cf. Simeon: Luke 2:25-32; Phil 3:3).
