I. This is his commission (v. 2): "Cause Jerusalem to know her abominations (that is, her sins); set them in order before her." Note, 1. Sins are not only provocations which God is angry at, but abominations which he hates, as contrary to his nature, and which we ought to hate, Jer. xliv. 4. 2. The sins of Jerusalem are in a special manner so. The practice of profaneness appears most odious in those that make a profession of religion. 3. Though Jerusalem is a place of great knowledge, yet she is loth to know her abominations; so partial are men in their own favour that they are hardly made to see and own their own badness, but deny it, palliate or extenuate it. 4. It is requisite that we should know our sins, that we may confess them, and may justify God in what he brings upon us for them. 5. It is the work of ministers to cause sinners, sinners in Jerusalem, to know their abominations, to set before them the glass of the law, that in it they may see their own deformities and defilements, to tell them plainly of their faults. Thou art the man.
