Charles Ellicott Commentary Acts 26:18

"to open their eyes, that they may turn from darkness to light and from the power of Satan unto God, that they may receive remission of sins and an inheritance among them that are sanctified by faith in me." — Acts 26:18 (ASV)

From darkness to light.—The words gain a fresh interest if we think of them as corresponding with the Apostle's own recovery from blindness. The imagery, though naturally common throughout Scripture, taking its place among the earliest and most widely received of the parables of the spiritual life, was specially characteristic of St. Paul. (2 Corinthians 4:6; Ephesians 5:8–13; Colossians 1:12; 1 Thessalonians 5:5.)

Among them which are sanctified by faith that is in me.—Better, have been sanctified; the Greek participle being in the perfect. The word, as always, expresses primarily the idea of a completed consecration rather than of a perfected holiness (Hebrews 9:13; Hebrews 10:10; Hebrews 13:12); but the one thought passes naturally into the other. The last six words may be connected grammatically either with “sanctified” or with “receive.” On internal grounds the latter is, perhaps, the best construction. Faith, i.e., is theoretically connected with “forgiveness of sins,” as well as with the “inheritance,” which implies sanctification.
