acts 26:18 To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me. - Free Bible Online

      18. To open their eyes, and to turn them from darkness to light--rather, "that they may turn" (as in Ac 26:20), that is, as the effect of their eyes being opened. The whole passage leans upon Isa 61:1 (Lu 4:18).
      and from the power of Satan--Note the connection here between being "turned from darkness" and "from the power of Satan," whose whole power over men lies in keeping them in the dark: hence he is called "the ruler of the darkness of this world." See on 2Co 4:4.
      that they may receive forgiveness . . . and inheritance among the sanctified by faith that is in me--Note: Faith is here made the instrument of salvation at once in its first stage, forgiveness, and its last, admission to the home of the sanctified; and the faith which introduces the soul to all this is emphatically declared by the glorified Redeemer to rest upon Himself--"FAITH, even THAT WHICH IS IN ME." And who that believes this can refrain from casting his crown before Him or resist offering Him supreme worship?
