2. The dominion of the prince by whom this ambassador is sent. (1.) He has authority to command him whom he sends: "I do send thee unto them, and therefore thou shalt say thus and thus unto them," v. 4. Note, it is the prerogative of Christ to send prophets and ministers and to enjoin them their work. St. Paul thanked Christ Jesus who put him into the ministry (1 Tim. i. 12); for, as he was sent of the Father, ministers are sent by him; and as he received the Spirit without measure he gives the Spirit by measure, saying, Receive you the Holy Ghost. They are impudent and rebellious, and yet I send thee unto them. Note, Christ gives the means of grace to many who he knows will not make a good use of those means, puts many a price into the hand of fools to get wisdom, who not only have no heart to it, but have their hearts turned against it. Thus he will magnify his own grace, justify his own judgment, leave them inexcusable, and make their condemnation more intolerable. (2.) He has authority by him to command those to whom he sends him: Thou shalt say unto them, Thus saith the Lord God. All he said to them must be spoken in God's name, enforced by his authority, and delivered as from him. Christ delivered his doctrines as a Son—Verily, verily, I say unto you; the prophets as servants—Thus saith the Lord God, our Master and yours. Note, The writings of the prophets are the word of God, and so are to be regarded by every one of us. (3.) He has authority to call those to an account to whom he sends his ambassadors. Whether they will hear or whether they will forbear, whether they will attend to the word or turn their backs upon it, they shall know that there has been a prophet among them, shall know by experience. [1.] If they hear and obey, they will know by comfortable experience that the word which did them good was brought to them by one that had a commission from God and a divine power going along with him in the execution of it. Thus those who were converted by St. Paul's preaching are said to be the seals of his apostleship, 1 Cor. ix. 2. When men's hearts are made to burn under the word, and their wills to bow to it, then they know and bear the witness in themselves that it is not the word of men, but of God. [2.] If they forbear, if they turn a deaf ear to the word (as it is to be feared they will, for they are a rebellious house), yet they shall be made to know that he whom they slighted was indeed a prophet, by the reproaches of their own consciences and the just judgments of God upon them for refusing him; they shall know it to their cost, know it to their confusion, know it by sad experience, what a pernicious dangerous thing it is to despise God's messengers. They shall know by the accomplishment of the threatenings that the prophet who denounced them was sent of God; thus the word will take hold of men, Zech. i. 6. Note, First, Those to whom the word of God is sent are upon their trial whether they will hear or whether they will forbear, and accordingly will their doom be. Secondly, Whether we be edified by the word or no, it is certain that God will be glorified and his word magnified and made honourable. Whether it be a savour of life unto life or of death unto death, either way it will appear to be of divine original.
