A.T. Robertson Commentary 1 Timothy 1:5

"But the end of the charge is love out of a pure heart and a good conscience and faith unfeigned:" — 1 Timothy 1:5 (ASV)

The end (το τελος). See Ro 6:21; 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 Ro 2:25), "and faith unfeigned" (κα πιστεως ανυποκριτου, late compound verbal in 2 Corinthians 6:6; Romans 12:9).
