Hugh Binning, Works, p. 24:
It is the unchangeable truth and immutable faithfulness of God that makes his word so sure; “it is builded up to the heavens.” Therefore the Psalmist often commends the word of the Lord as “a tried word;” as “purified seven times.” It hath endured the trial and proof of all men, – of all temptations, – of all generations. It hath often been put in the furnace of questions and doubtings, – it hath often been tried in the fire of afflictions, – but it came forth like pure gold, without dross. This is faith’s foundation, “God hath spoken in his holiness;” and therefore, though “all men be liars,” yet God will be found true: he deceives none, and is deceived of none.
