We have seen the complete ruin of the sinner; we have seen the complete remedy in Christ; let us now look at the result, as exhibited in whole-hearted consecration to the service of God. Isaiah had nothing to do for salvation, but he had plenty to do for his Saviour. He had nothing to do to get his sins purged, but plenty to do for the One who had purged them. Now he gave the willing, ready expression of obedience to God when, on hearing that a messenger was needed, he exclaimed, "Here am I; send me." This puts works in their proper place. The order is absolutely perfect. No one can do good works until he has experienced, in some degree, the action of the "throne" and the "altar." The light of the former must show him what he is, and the provisions of the latter must show him what Christ is ere he can say, "Here am I; send me."
