Job 13:18

Behold now, I have ordered [my] cause
Or "judgment" ^F20; that is, he had looked over his cause afresh, had reviewed the state of his case, had considered it in every light, had drawn a plan of it, had digested it in a proper manner, and had arranged his reasons and arguments in vindication of himself in a regular form; and had them at hand, and could readily and easily come at them on occasion, to vindicate himself; and upon the whole could say, in the strongest, manner, and could draw this conclusion,

I know that I shall be justified;
which, though it may primarily respect the case in dispute between him and his friends, and the charge of wickedness and hypocrisy brought against him by them, from which he doubted not he should upon a fair hearing be acquitted by God himself, yet it may include his whole state of justification, God-ward, in which he was and should continue; and so may respect, not only the justification of his cause before men, as it was ordered and managed by him, but also the justification of his person before God, of which he had a full assurance; having ordered his cause aright, settled matters well, and proceeded upon a good plan and foundation; which to do is not to put justification upon the foot of purity of nature at first birth, and a sober life and conversation from youth upward, and a perfection of good works arrived unto, as imagined; nor upon a comparative righteousness with respect to other men, even profane and ungodly persons; nor, upon repentance, and sincere though imperfect obedience; nor upon an external belief of evangelic truths, and a submission to Gospel ordinances: but such order their cause well, and rightly conclude their justification, who see and own themselves to be transgressors of the law of God, behold and acknowledge their own righteousness to be insufficient to justify them, view the righteousness of Christ revealed in the Gospel, in its glory, excellency, and suitableness, and lay hold upon it as their justifying righteousness; and observing that the word of God declares, that those that believe in Christ are and shall be justified, and finding in themselves that they do with the heart believe in Christ for righteousness, hence they most comfortably and most sensibly conclude that they are justified persons; for this knowledge is of faith, and this faith the faith of assurance; it is not barely for a man to know that there is righteousness in Christ, and justification by it, but that there is righteousness in him for himself, and that he is the Lord his righteousness; for the words may be rendered, "I know that I am righteous"; or, "am justified" ^F21; justification is a past act in the mind of God; it is present, as it terminates on the conscience of a believer; it is future, as it will be notified at the day of judgment before angels and men; see ( Isaiah 45:25 ) .
