Winslow on our justification

From Octavius Winslow's Morning Thoughts for the 20th of December:

You are often in fear that the righteousness of the law will rise against you; and when you consider your many failures and short-comings, you justly tremble. But fear not; for in Christ the law is perfectly fulfilled, and fulfilled in your stead, as much as if you had obeyed in your own person. Is not this a sure ground of comfort? You see the imperfection of your own obedience, and you are alarmed; but have you not an eye also for the perfection of Christ’s obedience, which He has made yours by imputation? "There is therefore now no condemnation to them who are in Christ Jesus," because He has fulfilled the law’s righteousness in their behalf. You are cast down because of the law of sin, but the Spirit of life has freed you from the law. You are troubled because of the law of God, but that law, by Christ’s perfect obedience, is fulfilled in you. You desire a righteousness that will present you without spot before God; you have it in Him who is the "Lord our righteousness." Christian! Christ’s whole obedience is yours. What can sin, or Satan, or conscience, or the law itself allege against you now? Be humble, and mourn over the many flaws and failures in your obedience; yet withal rejoice, and glory, and make your boast in the fullness, perfection, and unchangeableness of that righteousness on the Incarnate God which will place you without fault before the throne.
