And He shall bring forth thy righteousness as the light, and thy judgment as the noonday. -Psalm 37:6

Ask for the sinner, Justice! Let the voice of Justice cry, “Bring forth the sinner!” The sinner is brought. Who doth the executioner lead forth? It is the incarnate Son of God. True, He did not commit the sin; He was without fault; but it is imputed to Him: He stands in the sinner’s place. Now Justice cries, “Bring forth the righteous, the perfectly righteous.” Whom do I see? Lo, the Church is brought; each believer is brought. Justice says, “Are these perfectly righteous?” “Yes they are. What Christ did is theirs; what they did is laid on Christ; His righteousness is theirs; their sins are His.” I appeal to you, ye ungodly. This seems strange and startling, does it not? …and you laugh at it. Set it down for what you please, sirs. God has set it up as His truth; He has made us righteous through the imputed righteousness of Jesus Christ. And now, if I am a true believer, I stand here freed from every sin. There is not a crime against me in the book of God; it is blotted out for ever; it is cancelled; and not only can I never be punished, but I have nothing to be punished for. Christ has atoned for my sins, and I have received His righteousness.

“Saviour, if of Zion’s city,
I, by grace, a member am,
Let the world revile or pity,
I will glory in Thy name.”
