2. The consent of Isaiah to it: Then said I, Here am I; send me. He was to go on a melancholy errand; the office seemed to go a begging, and every body declined it, and yet Isaiah offered himself to the service. It is an honour to be singular in appearing for God, Judges v. 7. We must not say, "I would go if I thought I should have success;" but, "I will go, and leave the success to God. Here am I; send me." Isaiah had been himself in a melancholy frame (v. 5), full of doubts and fears; but now that he had the assurance of the pardon of his sin the clouds were blown over, and he was fit for service and forward to it. What he says denotes, (1.) His readiness: "Here am I, a volunteer, not pressed into the service." Behold me; so the word is. God says to us, Behold me (ch. lxv. 1), and, Here I am (ch. lviii. 9), even before we call; let us say so to him when he does call. (2.) His resolution; "Here I am, ready to encounter the greatest difficulties. I have set my face as a flint." Compare this with ch. l. 4-7. (3.) His referring himself to God: "Send me whither thou wilt; make what use thou pleasest of me. Send me, that is, Lord, give me commission and full instruction; send me, and then, no doubt, thou wilt stand by me." It is a great comfort to those whom God sends that they go for God, and may therefore speak in his name, as having authority, and be assured that he will bear them out.
