I. The command which God gave to Jeremiah to write a summary of his sermons, of all the reproofs and all the warnings he had given in God's name to his people, ever since he first began to be a preacher, in the thirteenth year of Josiah, to this day, which was in the fourth year of Jehoiakim, v. 2, 3. What had been only spoken must now be written, that it might be reviewed, and that it might spread the further and last the longer. What had been spoken at large, with frequent repetitions of the same things, perhaps in the same words (which has its advantage one way), must now be contracted and put into less compass, that the several parts of it might be better compared together, which has its advantage another way. What they had heard once must be recapitulated, and rehearsed to them again, that what was forgotten might be called to mind again and what made no impression upon them at the first hearing might take hold of them when they heard it the second time. And what was perhaps already written, and published in single sermons, must be collected into one volume, that none might be lost. Note, The writing of the scripture is by divine appointment. And observe the reason here given for the writing of this roll (v. 3): It may be the house of Judah will hear. Not that the divine prescience was at any uncertainty concerning the event: with that there is no peradventure; God knew certainly that they would deal very treacherously, Isa. xlviii. 8. But the divine wisdom directed to this as a proper means for attaining the desired end: and, if it failed, they would be the more inexcusable. And, though God foresaw that they would not hear, he did not tell the prophet so, but prescribed this method to him as a probably one to be used, in the hopes that they would hear, that is, heed and regard what they heard, take notice of it and mix faith with it: for otherwise our hearing the word, though an angel from heaven were to read or preach it to us, would stand us in no stead. Now observe here, 1. What it is hoped they will thus hear: All that evil which I purpose to do unto them. Note, The serious consideration of the certain fatal consequences of sin will be of great use to us to bring us to God. 2. What it is hoped will be produced thereby: They will hear, that they may return every man from his evil way. Note, The conversion of sinners from their evil courses is that which ministers should aim at in preaching; and people hear the word in vain if that point be not gained with them. To what purpose do we hear of the evil God will bring upon us for sin if we continue, notwithstanding, to do evil against him? 3. Of what vast advantage their consideration and conversion will be to them: That I may forgive their iniquity. This plainly implies the honour of God's justice, with which it is not consistent that he should forgive the sin unless the sinner repent of it and turn from it; but it plainly expresses the honour of his mercy, that he is very ready to forgive sin and only waits till the sinner be qualified to receive forgiveness, and therefore uses various means to bring us to repentance, that he may forgive.
