john 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: - Free Bible Online

      12. But as many--individuals, of the "disobedient and gainsaying people."
      gave he power--The word signifies both authority and ability, and both are certainly meant here.
      to become--Mark these words: Jesus is the Son of God; He is never said to have become such.
      the sons--or more simply, "sons of God," in name and in nature.
      believe on his name--a phrase never used in Scripture of any mere creature, to express the credit given to human testimony, even of prophets or apostles, inasmuch it carries with it the idea of trust proper only towards GOD. In this sense of supreme faith, as due to Him who "gives those that believe in Himself power to become sons of God," it is manifestly used here.
