Integrity

If ever there was a man of integrity it was Isaiah Ben Amoz. He was a whole man, a together type of a fellow. He was considered by his contemporaries as the most righteous man in the nation. He was respected as a paragon of virtue. Then he caught one sudden glimpse of a Holy God. In that single moment all of his self-esteem was shattered. In a brief second he was exposed, made naked beneath the gaze of the absolute standard of holiness. As long as Isaiah could compare himself to other mortals, he was able to sustain a lofty opinion of his own character. The instant he measured himself by the ultimate standard, he was destroyed - morally and spiritually annihilated. He was undone. He came apart. His sense of integrity collapsed.
