In this post we will examine the Abrahamic covenant, in its four different references (Gen. 12:1-3; 13:14-17; 15:1-21; 17:1-21; and 22:15-18), and show the provisions of the covenant in three different categories: as individual promises (to Abraham and Sarah), as national promises (to Abraham’s seed), and as universal promises (to all nations, or to Gentiles). Note these categories on the chart.
Notice, if you have looked at the charts (sorry they are so blurry), that the church isn’t included. That is because, indeed, the Abrahamic covenant was made only to Israel. However, we know that the church wouldn’t exist without the promises of God to Abraham. Let me take just a few minutes to explain. Though the Abrahamic covenant was made exclusively for the Jews, there is a provision made in the covenant for all people—Jews and Gentiles; for in Genesis 12:3 and 22:18, God promised that in Abraham and in his seed all the nations of the earth would be blessed. This blessing is both spiritual and material, and the spiritual part comes to anyone who believes in God as Abraham did. In fact, all who believe become Abraham’s children (Rom. 9:8) and they are called God’s people. Look at this passage in Romans.
even us, whom He also called, not from among Jews only, but also from among Gentiles. 25 As He says also in Hosea,
“I will call those who were not My people, ‘My people,’
And her who was not beloved, ‘beloved.'”
26 “And it shall be that in the place where it was said to them, ‘ you are not My people,’
There they shall be called sons of the living God.”
Yes, all non-Jews (Gentiles) who believe can partake of the spiritual blessings of the Abrahamic covenant. That is, we can reap the blessings of the New covenant given to Abraham. This comes to Gentiles in the same way it comes to Jews—through faith in Jesus Christ, who Himself is of the seed of Abraham and of David.
Indeed, Christ Himself is the promised blessing to all nations. He is of the seed of Abraham and is the mediator of the New covenant (Heb. 12:24). This New covenant, He said, is in His blood (Lu. 22:20); thus we receive the blessing of it (salvation) through His death; He paid the penalty for our sin and gave us eternal life when we believed.
