Galatians 3:29 tells us that we are children of Abraham based on the fact that we are in Christ. As Gentiles that he was largely writing to, it would have been crazy to say that non-Jews are children of Abraham. But that is not so with Christ. As He was a true Jew, so whoever is in Him, i.e., whoever is represented by Him, is also a Jew through Him. All Christians are children of Abraham not because they are physical descendants of Abraham, but because they are united to Christ, the true child of Abraham, and through Him, they are also children of Abraham. It is in light of this that Paul calls believers the Israel Of God in Galatians 6:16. This is likewise the case of the believers, both Jewish and Gentile being the Israel Of God. As they are in Him who is the Servant of the LORD in Isaiah, who is called Israel (Isa. 41:8; 49:1-7), so likewise as they were through Him children of Abraham, they are also the Israel Of God. This is also seen from Ephesians 2:11ff, where we are told that believing Jews and believing Gentiles, have become one new man. That would be the New Israel or Spiritual/True Israel. We were made citizens of “the commonwealth of Israel” in Christ (Eph. 2:12-13, 19).
From Ephesians 2, Paul continues the discussion underhand concerning believing Jews and Gentiles. In Ephesians 3:6, Paul speaks of a mystery, something that was hidden, but now revealed. This mystery is the fact that the believing Gentiles belong to the same body as the believing Jews, that is, they belong to the commonwealth of Israel. They belong to Abraham to whom the promises of God were made concerning having offspring as the stars of heaven. The believing Gentiles will inherit along with the believing Jews the promises made to Israel in the OT as all the promises of God find their Yes (fulfillment) in Him and His body (2 Cor. 1:20).
Our inheritance consists of us obtaining eternal life, the New Heavens and New Earth, i.e., the consummated Kingdom of God—the New Jerusalem. Becoming spiritual Jews in Christ. Becoming the Israel Of God in Christ. Becoming co-heirs in everything that Christ has inherited from the Father. Glory to the God Who has planned this from long ago and purposed to bless us, undeserving sinners in the Beloved.
§6 The virtue, efficacy, and benefit thereof were communicated to the elect in all ages
- Although the price of redemption was not actually paid by Christ till after his incarnation, yet the virtue, efficacy, and benefit thereof were communicated to the elect in all ages, successively from the beginning of the world, 1 in and by those promises, types, and sacrifices wherein he was revealed, and signified to be the seed which should bruise the serpent’s head; 2 and the Lamb slain from the foundation of the world, 3 being the same yesterday, and to-day and for ever. 4

The price of redemption was paid by Christ...after His incarnation, at the cross (Gal. 3:13; 4:4-5). But this does not mean that its effect did not apply to those who were in happy communion with God. In fact, chapter 7:3 it is said of the Covenant of Grace that “it is alone by the grace of this covenant that all the posterity of fallen Adam that ever were saved did obtain life and blessed immortality”. This is the covenant of salvation by Christ. Chapter 7:2 says the following about this “covenant of grace, wherein he ...
