Galatians 6:16

As many as walk according to this rule - Τῳ κανονι τουτῳ· This canon; viz. what is laid down in the preceding verses, that redemption is through the sacrifice of Christ; that circumcision and uncircumcision are equally unavailable; and that none can be saved without being created anew. This is the grand canon or rule in Christianity.

Peace be on them - Those who act from this conviction will have the peace and mercy of God; for it is in this way that mercy is communicated and peace obtained.

The Israel of God - The true Christians, called here the Israel of God, to distinguish them from Israel according to the flesh. See the notes on Romans 2:29; Romans 4:12 (note).

And as many as walk - As many as live, for so the word walk is used in the Scriptures. According to this rule. Greek: "This canon"; see the word explained in the notes at 2 Corinthians 10:13.

Peace be on them - See the note at Romans 15:33.

And upon the Israel of God - The true church of God; all who are his true worshippers; see the note at Romans 2:28-29; Romans 9:6, note.

6:16 And as many as walk according to this rule - Glorying only in the cross of Christ. Being crucified to the world. And, Created anew. Peace and mercy be upon them, and upon the Israel, that is, the Church, of God - Which consists of all those, and those only, of every nation and kindred, who walk by this rule.
