Reproofs: To Be Given in Love. Preaching on John 13:14 : the duty of disciples to wash one another’s feet: Mr. Finlayson, of Helmsdale, observed, “One way in which disciples wash one another’s feet is by reproving one another. but the reproof must not be couched in angry words, so as to destroy the effect; nor in tame, so as to fail of effect. Just as in washing a brother’s feet, you must not use boiling water to scald, nor frozen water to freeze them.”
