Here, I. The prophet experiences a divine power going along with him in his work, and he makes a solemn profession and protestation of it, as that which would justify him, and bear him out, in his plain dealing with the princes and rulers. He would not, he durst not, make thus bold with the great men, but that he was carried out to do it by a prophetical impulse and impression. It was not he that said it, but God by him, and he could not but speak the word that God put into his mouth. It comes in likewise by way of opposition to the false prophets, who were full of shame when they lived to see themselves proved liars, and who never had courage to deal faithfully with the people, but flattered them in their sins; they were sensual, not having the Spirit, but truly (says Micah) I am full of power by the Spirit of the Lord, v. 8. Having in himself an assurance of the truth of what he said, he said it with assurance. Compare him with those false prophets, and you will say, There is no comparison between them. What is the chaff to the wheat? Jer. xxiii. 28. What is painted fire to real fire? Observe here, 1. What the qualifications were with which this prophet was endured: He was full of power, and of judgment, and of might; he had an ardent love to God and to the souls of men, a deep concern for his glory and their salvation, and a flaming zeal against sin. He had likewise courage to reprove it and witness against it, not fearing the wrath either of great men or of great multitudes; whatever difficulties or discouragements he met with, they did not deter him nor drive him from his work; none of these things moved him. And all this was guided by judgment and discretion; he was a man of wisdom as well as courage; in all his preaching there was light as well as heat, and a spirit of wisdom as well as of zeal. Thus was this man of God thoroughly furnished for every good word he had to say, and every good work he had to do. Those he preached to could not but perceive him to be full both of power and judgment, for they found both their understandings opened and their hearts made to burn within them, with such evidence and demonstration, and with such power, did the word come from him. 2. Whence he had these qualifications, not from and of himself, but he was full of power by the Spirit of the Lord. Knowing that it was indeed the Spirit of the Lord that was in him, and spoke by him, that it was a divine revelation that he delivered, he spoke it boldly, and as one having authority, set his face as a flint, knowing he should be justified and borne out in what he said, Isa. l. 7, 8. Note, Those who act honestly may act boldly; and those who are sure that they have a commission from God need not be afraid of opposition from men. Nay, he had not only a Spirit of prophecy, which was the ground of his boldness, but the Spirit of sanctification endued him with the boldness and wisdom which were requisite for him. It was not in any strength of his own that he was strong; for who is sufficient for these things? but in the Lord, and in the power of his might; for from him all our sufficiency is. Are we full of power at any time, for that which is good? It is purely by the Spirit of the Lord, for of ourselves we are weak as water; it is the God of Israel that gives strength and power both to his people and to his ministers. 3. What use he made of these qualifications—this judgment and this power; he declared to Jacob his transgression and to Israel his sin. If transgression be found in Jacob and Israel, they must be told of it, and it is the business of God's prophets to tell them of it, to cry aloud and not to spare, Isa. lviii. 1. Those who come to hear the word of God must be willing to be told of their faults, and must not only give their ministers leave to deal plainly and faithfully with them, but take it kindly, and be thankful; but, since few have meekness enough to receive reproof, those have need of a great deal of boldness who are to give reproofs, and must pray for a spirit both of wisdom and might.
