The expositor of scripture must keep in mind that the words of Holy Writ are of Divine origin and are verbally inspired
IT is of first importance that the expositor should constantly bear in mind that not only are the substance and the sentiments expressed in Holy Writ of Divine origin, but that the whole of its contents are verbally inspired. Its own affirmations lay considerable emphasis upon that fact. Said holy Job,
“I have esteemed the words of His mouth more than my necessary food” (23:12):
he not only venerated God’s Word in its entirety, but highly prized each syllable in it.
“The words of the Lord are pure words: as silver tried in a furnace of earth, purified seven times” (Psalm 12:6).
We believe that is more than a general statement concerning the preciousness, purity and permanence of what proceeds out of the mouth of Jehovah, for it is to be duly noted that the Divine utterances are not simply likened to silver tried in a furnace, but to “a furnace of earth.” Though the Holy Spirit has employed the vernacular of earth, yet He has purged what He uses from all human dross, giving some of His terms an entirely different force from their human original, investing many of them with a higher meaning, and applying all with spiritual perfection—as the “purified seven times” purports. Thus, “every word of God is pure” (Proverbs 30:5).
