17:28 in him we live. The God of creation sustains the very life of every person, even those who don’t believe He exists, so that “He [is] not far from every one of us” (Acts 17:27). Note also Colossians 1:17; Hebrews 1:3; etc.

17:28 poets. Paul here seems to be referring to Epimenides, Aratus and Cleanthes, each of whom seemed to have had some insight, however attained, into the fact that one supreme God had created all men. We are all the “offspring” (Greek genos) of God by creation (Malachi 2:10). This, of course, does not mean that all are children of God spiritually. This requires the new birth by faith in Christ (e.g., John 1:12-13).
