16 And as many as walk according to this rule, peace and mercy be upon them, and upon the Israel of God. 17 From now on let no one trouble me, for I bear in my body the marks of the Lord Jesus. (Galatians 6:16–17, NKJV)
The nation of Israel was chosen by God, fulfilling a promise He made to Abraham to make his seed a great nation (Gen. 12:2; Deut. 10:22). God told Israel through Moses, “‘Now therefore, if you will indeed obey My voice and keep My covenant, then you shall be a special treasure to Me above all people; for all the earth is Mine. And you shall be to Me a kingdom of priests and a holy nation.’ These are the words which you shall speak to the children of Israel” (Exo. 19:5-6). Sadly, Israel often rebelled against God. Their crowning rebellion was rejecting the promised Messiah. As a result, the kingdom was taken from Israel and given to Christ’s kingdom, His church (Matt. 21:42-45; Heb. 12:28; 1 Pet. 2:4-10). Because His kingdom is “not of this world,” physical descend and possessing land do not define “the Israel of God” in this gospel age. Faith, not flesh, identifies the children of God (Israel) now (Rom. 2:25-29; 9:6-8). No longer does physical lineage and circumcision of the flesh by the Law of Moses. Now, the gospel of the cross of Christ produces and identifies God’s chosen people (Gal. 3:26-29). Paul experienced great physical suffering for Christ and the gospel. Yet, God’s peace and mercy rested on him and on all who walk according to the standard of truth, the gospel, that God’s Spirit revealed through the apostles and prophets of Christ (Gal. 3:1-3; 5:7, 16-26).
