(2.) It shall turn for a testimony against those that are resolved to go on in their wickedness, v. 5. This is the direct answer to their challenge, "Where is the God of judgment? You shall know where he is, and shall know it to your terror and confusion, for I will come near to you to judgment; to you that set divine justice at defiance." To them the gospel of Christ will be a savour of death unto death; it will bind them over to condemnation and will judge them in the great day, John xii. 48. Let us see here, [1.] Who the sinners are that must appear to be judged by the gospel of Christ. They are the sorcerers, who died in spiritual wickedness, that forsake the oracles of the God of truth to consult the father of lies; and the adulterers, who wallow in the lusts of the flesh, those adulterers who were charged with dealing treacherously (ch. ii. 15); and the false swearers, who profane God's name and affront his justice, by calling him to witness to a lie; and the oppressors, who barbarously injure and trample upon those who lie at their mercy, and are not able to help themselves: they defraud the hireling in his wages and will not give him what he agreed for; they crush the widow and fatherless, and will not pay them their just debts, because they cannot prove them, or have not wherewithal to sue for them; the poor stranger too, who has no friend to stand by him and is ignorant of the laws of the country, they turn aside from his right, so that he cannot keep or cannot recover his own. That which is at the bottom of all this is, They fear not me, saith the Lord of hosts. The transgression of the wicked plainly declares that there is no fear of God before his eyes. Where no fear of God is no good is to be expected. [2.] Who will appear against them: I will come near, says God, and will be a swift witness against them. They justify themselves, and, their sins having been artfully concealed, hope to escape punishment for want of proof; but God, who sees and knows all things, will himself be witness against them, and his omniscience is instead of a thousand witnesses, for to it the sinner's own conscience shall be made to subscribe, and so every mouth shall be stopped. He will be a swift witness; though they reflect upon him as slow and dilatory, and ask, Where is the God of judgment, and where the promise of his coming? they will find that he is not slack concerning his threatenings any more than he is concerning his promises. Judgment against those sinners shall not be put off for want of evidence, for he will be a swift witness. His judgment shall overtake them, and it shall be impossible for them to outrun it. Evil pursues sinners.
