17:26 of one blood. The concept of “race” has no basis in Scripture; all men are descended from Adam, through Noah, and thus all are members of only one race—the human race. The term “race,” as ordinarily used, is strictly an evolutionary concept, with “race” understood as a sub-species in the process of evolving into a new species. There is no observational scientific evidence for such evolutionary transformations, among either men or animals.

17:26 bounds of their habitation. In ways unknown, yet real, God raises nations up and puts them down, as He will (note Deuteronomy 32:7-9; Daniel 2:20-21; etc.), in accordance with their faithfulness to His respective purposes for them. “Blessed is the nation whose God is the LORD” (Psalm 33:12). “The wicked shall be turned into hell, and all the nations that forget God” (Psalm 9:17).

17:29 Godhead. This is the first of three New Testament references to the “Godhead” (see also Romans 1:20; Colossians 2:9). Each translates a slightly different Greek noun, but all refer essentially to the “Godhood” of God—that is, the nature or structure of God, to God as He has revealed Himself. Since He has revealed Himself as a triune God (Father, Son, Spirit), the term has commonly been used to refer to the Trinity. In this verse, we are told that God can never be represented by an image or model which man can make, either with his hands or his mind. However, what man cannot do, God has done. That is, He has constructed a marvelous model of the Godhead in His creation. See notes on Romans 1:20.
