IV. Let them know that, as their own wickedness was the procuring cause of these judgments, so they shall not be removed till they have done their work, v. 5. When God has come forth to contend with a sinful people it is necessary that they should understand, 1. That it is their own sin that has entangled them; for can a bird fall in a snare upon the earth where no gin is for him? No, nature does not lay snares for the creatures, but the art of men; a bird is not taken in a snare by chance, but with the fowler's design; so the providence of God prepares trouble for sinners, and it is in the work of their own hands that they are snared. Affliction does not spring out of the dust, but it is God's justice, and our own wickedness, that correct us. 2. It is nothing but their own repentance that can disentangle them; for shall one take up a snare from the earth, which he laid with design, except he have taken something as he designed? So neither will God remove the affliction he has sent till it have done its work and accomplished that for which he sent it. If our hearts be duly humbled, and we are brought by our afflictions to confess and forsake our sins, then the snare has taken something, then the point is gained, the end is answered, and then, and not till then, the snare is broken, is taken up from the earth, and we are delivered in love and mercy.
