Sunday, we continued our study of Eph. 2:11‑16, watching as God nullified Satan's attempt to nullify God's Prophetic Program with the Nation of Israel. He did this by dismantling His Prophetic Program with the Nation of Israel while beginning a new Mystery Program with the Body of Christ.
Gen. 17 Questions
God gave Abraham circumcision in Gen. 17 to remind Israel of their responsibility to be the conduit of His blessings to the world, the Gentile world. While, yes, circumcision separated His own Nation of Israel from the Gentile nations, its intention wasn't to exclude the Gentiles from God and His things but to bring them to God and into His things by providing a safe, holy and righteous place where they could worship the one true God with Israel and through her rise (Ex. 18:8‑12; Is. 60).
CONTEXT OF GEN. 17
Once it is established that Abraham had believed in the LORD and He counted it to him for righteousness in Gen. 15:6, God codified the promises He made to Abraham in a covenant, the Abrahamic Covenant (Gen. 15:9-21). In it, God granted Abraham and his descendants an inheritance that included a miraculous seed, Isaac, and countless progeny (Gen. 17:1‑5), whom He would deliver from Egypt as a nation and plant in the Land of Canaan (Gen. 17:7, 18‑21)—Seed, Descendants, Nation and Land.
Immediately after this, Abraham lapsed into unfaithfulness in Gen. 16. He tried to accomplish through the power of his own flesh what only God could do through His supernatural power—produce a child from union of barren and elderly Abraham and Sarah. Instead of waiting on God for the promised child with Sarah, he produced a child with Sarah's maid, Hagar, whose name was Ishmael. Earlier, God rejected Abraham's plan to let his servant Eliezer of Damascus be his heir (Gen. 15:1‑3), and here He rejected Abraham's plan to let Ishmael be his heir as well (Gen. 16).
In response to Abraham's failure in Gen. 16, God bolstered his faith with an appearance through which He gave him two signs in Gen. 17 that confirmed God's promises to Abraham as codified in the Abrahamic Covenant in Gen. 15. First, the LORD changed his name from Abram to Abraham—a father of many nations (Gen. 17:5). Second, He gave him the sign of circumcision (Gen. 17:11).
ADDITIONAL COVENANT OR A SIGN ADDED TO THE ABRAHAMIC COVENANT?
Is the covenant referred to in Gen. 17 the Abrahamic Covenant from Gen. 15, or another covenant that must be distinguished from the Abrahamic Covenant. Many think the latter conclusion for a couple of reasons. First, the LORD tells Abraham that I WILL make a covenant between Me and thee (Gen. 17:2), which sounds like this is a covenant He will “make” with Abraham in the future, and cannot, therefore, be the Abrahamic Covenant, which He “made” with Abraham in the past (Gen. 15). Second, this covenant appears to be dependent on human contribution/faithfulness (Gen. 17:2), whereas the Abrahamic Covenant is not (Gen. 18:12).
But this explanation is not required if we understand that the Hebrew words for “make/made” in Gen. 15 and 17 are different. In Gen. 15, the underlying Hebrew word is “karat,” which means “to cut” and came to mean in itself “to cut a covenant.” The underlying Hebrew word in Gen. 17, however, is “natan,” which means “to set forth,” to set in motion” or “begin to implement.” So, whereas the Abrahamic Covenant was “cut” and created in Gen. 15, God promised that He will set it into motion and begin implementing it as Abraham walked before Him in faith in Gen. 17. Then he would be “perfect,” complete for he will reach the end goal of the Abrahamic Covenant—Israel being a blessing to the whole world. And it is interesting that in Gen. 18, God begins teaching Abraham His friend how to be a blessing to righteous Gentiles.
Once we appreciate this, the second problem is resolved as well. While the Abrahamic Covenant is a Grace Covenant that God will carry out with 100% certainty, He has chosen to accomplish it not on behalf of unbelieving and unfaithful Israel but on behalf of believing and faithful Israel. It will ultimately and completely be fulfilled at Christ's 2nd Coming when believing Israel is ushered into her earthly Kingdom.
In conclusion, God does not introduce a new additional covenant in Gen. 17. Rather He promises to set in motion the Abrahamic Covenant for believing Abraham/Israel as he/they fulfill their purpose of being a blessing to Gentiles. Which is exactly what we see Abraham doing in Gen. 18.
