9. Let love be without dissimulation--"Let your love be unfeigned" (as in 2Co 6:6; 1Pe 2:22; and see 1Jo 3:18).
      Abhor that which is evil; cleave to that which is good--What a lofty tone of moral principle and feeling is here inculcated! It is not, Abstain from the one, and do the other; nor, Turn away from the one, and draw to the other; but, Abhor the one, and cling, with deepest sympathy, to the other.
