II. Observe how corrupt their principles were, to which were owing all these corrupt practices. Let us trace up the streams to the fountain (v. 17): You have wearied the Lord with your words. They thought to evade the convictions of the word, and to justify themselves by cavilling with God's proceedings; but their defence was their offence, and their vindication of themselves was the aggravation of their crime; they affronted the Lord with their words, and repeated them so often, and persisted so long in their contradictions, that they even wearied him; see Isa. vii. 13. They made him weary of doing them good as he had done, and stopped the current of his favours; or they represented him as weary of governing the world, and willing to quit it and lay aside the care of it. Note, It is a wearisome thing, even to God himself, to hear people insist upon their own justification in their corrupt and wicked practices, and plead their atheistical principles in vindication of them. But, as if God by his prophet had done them wrong, see how impudently they ask, Wherein have we wearied him? What are those vexatious words whereby we have wearied him? Note, Sinful words are more offensive to the God of heaven than they are commonly thought to be. But God has his proofs ready; two things they had said, at least in their hearts (and thoughts are words to God), with which they had wearied him:—1. They had denied him to be a holy God, and had asserted that concerning him which is directly contrary to the doctrine of his holiness. As he is a holy God, he hates sin, is of purer eyes than to behold it, and cannot endure to look upon it, Hab. i. 13. He is not a God that has pleasure in wickedness, Ps. v. 4. And yet they had the impudence to say, in direct contradiction to this, Every one that does evil is good in the sight of the Lord, and he delights in them. This wicked inference they drew, without any reason, from the prosperity of sinners in their sinful courses (see ch. iii. 15), as if God's love or hatred were to be known by that which is before us, and those must be concluded good in the sight of the Lord who are rich in the world. Or this they said because they wished it might be so; they were resolved to do evil, and yet to think themselves good in the sight of the Lord, and to believe that he delighted in them, notwithstanding; and therefore, under pretence of making God not so severe as he was commonly represented, they said as they would have it, and thought he was altogether such a one as themselves. Note, Those who think God a friend to sin affront him and deceive themselves. 2. They had denied him to be the righteous governor of the world. If he did not delight in sin and sinners, yet it would serve their turn to believe that he would never punish it or them. They said, "Where is the God of judgment? That God who, we have been so often told, would call us to an account, and reckon with us for what we have said and done—where is he? He has forsaken the earth, and takes no notice of what is said and done there; he has said that he will come to judgment; but where is the promise of his coming? We may do what we please; he sees us not, nor will regard us." It is such a challenge to the Judge of the whole earth as bids defiance to his justice, and, in effect, dares him to do his worst. Such scoffers as these there were in the latter days of the Jewish church, and such there shall be in the latter days of the Christian church; but their unbelief shall not make the promise of God of no effect; for the day of the Lord will come. Behold, the Judge stands before the door; the God of judgment is at hand.
