The end (το τελος). See Romans 6:21; Romans 10:4 for τελος (the good aimed at, reached, result, end).

Love (αγαπη). Not "questionings." Romans 13:9. "Three conditions for the growth of love" (Parry): "Out of a pure heart" (εκ καθαρας καρδιας, O.T. conception), "and a good conscience" (κα συνειδησεως αγαθης, for which see Romans 2:25), "and faith unfeigned" (κα πιστεως ανυποκριτου, late compound verbal in 2. Corinthians 6:6; Romans 12:9).
