“A spotless, pure, complete, and incomparable righteousness” by Thomas Brooks:
“A second property of an humble soul is this, He overlooks his own righteousness, and lives upon the righteousness of another, to wit, the Lord Jesus. So the apostle, (Philip. 3:8–10), overlooks his own righteousness, and lives wholly upon the righteousness of Christ: ‘I desire to be found in him,’ saith he, ‘not having mine own righteousness.’
Away with it, it is dross, it is dung, it is dog’s meat! It is a rotten righteousness, an imperfect righteousness, a weak righteousness, ‘which is of the law; but that which is through the faith of Christ, the righteousness which is of God by faith,’ that is a spotless righteousness, a pure righteousness, a complete righteousness, an incomparable righteousness; and, therefore, an humble soul overlooks his own righteousness, and lives upon Christ’s righteousness.
Remember this, all the sighing, mourning, sobbing, and complaining in the world, doth not so undeniably evidence a man to be humble, as his overlooking his own righteousness, and living really and purely upon the righteousness of Christ. This is the greatest demonstration of humility that can be shewn by man, (Mat. 6:8).
Men may do much, hear much, pray much, fast much, and give much, &c., and yet be as proud as Lucifer, as you may see in the Scribes, Pharisees, Mat. 23, and those in Isa, 58:3, who in the pride of their hearts made an idol of their own righteousness: ‘Wherefore have we fasted,’ say they, ‘and thou seest it not? wherefore have we afflicted our souls, and thou takest no knowledge?’
Oh! but for a man now to trample upon his own righteousness, and to live wholly upon the righteousness of another, this speaks out a man to be humble indeed. There is nothing that the heart of man stands more averse to than this, of coming off from his own righteousness.
Man is a creature apt to warm himself with the sparks of his own fire, though he doth lie down for it in eternal sorrow, Isa. 50:11. Man is naturally prone to go about to establish his own righteousness, that he might not subject to the righteousness of Christ; he will labour as for life, to lift up his own righteousness, and to make a saviour of it, Rom. 10:4.
Ay, but an humble soul disclaims his own righteousness: ‘All our righteousness is as filthy rags.’ ‘Enter not into judgment with thy servant, for in thy sight shall no man living be justified,’ Ps. 143:2. So Job, ‘Though I were righteous, yet I would not answer, but I would make supplication to my judge,’ Job 9:15.
Proud Pharisees bless themselves in their own righteousness: ‘I thank God I am not as this publican; I fast twice in the week,’ &c., Luke 18:11, 12. Ay, but now a soul truly humbled blushes to see his own righteousness, and glories in this, that he has the righteousness of Christ to live upon.2 Rev. 4:10, 11, the twenty-four elders throw down their crowns at the feet of Christ.
By their crowns you may understand their gifts, their excellencies, their righteousness; they throw down these before Christ’s throne, to note to us, that they did not put confidence in them, and that Christ was the crown of crowns and the top of all their royalty and glory. An humble soul looks upon Christ’s righteousness as his only crown.”
