For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him. -2Corinthians 5:21

Jesus, the eternal Son of God, “very God of very God,” who had been hymned through eternal ages by joyous angels, who had been the favourite of His Father’s court, exalted high above principalities and powers, and every name that is named, He Himself condescended to become man; was born of the Virgin Mary; was cradled in a manger; lived a life of suffering, and at last died a death of agony. If you will but think of the wondrous person whom Jesus was-as very God of very God, king of angels, creator, preserver, Lord of all-I think you will see that in His sufferings, the law received a greater vindication than it could have done even in the sufferings of all the men that have ever lived or ever could live. If God had consumed the whole human race, if all the worlds that float in ether had been sacrificed as one mighty holocaust to the vengeance of the law, it would not have been so well vindicated as when Jesus died. For the deaths of all men and all angels would have been but the deaths and sufferings of creatures; but when Jesus died, the Creator Himself underwent the pang, it was the divine preserver of the world hanging on the cross. There is such dignity in the Godhead, that all it does is marvelous and infinite in its merit; and when He stooped to suffer, when He bowed His awful head, cast aside His diadem of stars to have His brow girt about with thorns; when His hands that once swayed the sceptre of all worlds were nailed to the tree; when His feet that erst had pressed the clouds, when these were fastened to the wood, then did the law receive an honour such as it never could have received if a whole universe in one devouring conflagration had blazed and burned for ever.~ C.H. Spurgeon

To declare, I say, at this time His righteousness: that He might be just, and the justifier of him which believeth in Jesus. -Romans 3:26

Justice has been satisfied through the substitution of our blessed Lord and Saviour, Jesus Christ. When man sinned the law demanded that man must be punished. The first offense of man was committed by Adam, who was the representative of the entire race. When God would punish sin, in His own infinite mind He thought of the blessed expedient, not of punishing His people, but of punishing their representative, the covenant head, the second Adam. It was by one man, the first man, that sin entered into the world, and death by sin. It was by another man, the second Adam, who is the Lord from heaven, it was by Him that this sin was borne; by Him its punishment was endured; by Him the whole wrath of heaven was suffered. And through that second representative of manhood, Jesus, the second Adam, God is now able and willing to forgive the vilest of the vile, and justify even the ungodly, and He is able to do so without the slightest violation of His justice. For, mark, when Jesus Christ the Son of God suffered on the tree, He did not suffer for Himself. He had no sin, either natural or actual. He had done nothing whatever that could bring Him under the ban of heaven, or subject His holy soul and His perfect body to grief and pain. When He suffered it was as a substitute. He died-“the just for the unjust, that He might bring us to God.” Had His sorrows been personally deserved they would have had no efficacy in them. But inasmuch as for sins not His own He died to atone; inasmuch as He was punished, not for any guilt that He had done or could do, but for the guilt incurred by others, there was a merit and an efficacy in all that He suffered, by which the law was satisfied, and God is able to forgive.~ C.H. Spurgeon

If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. -1John 1:9

When the soul is seriously impressed with the conviction of its guilt, when terror and alarm get hold upon it concerning the inevitable consequences of its sin, the soul is afraid of God. It dreads at that time every attribute of divinity. But most of all the sinner is afraid of God’s justice. “Ah,” saith he to himself, “God is a just God; and if so, how can He pardon my sins? for my iniquities cry aloud for punishment, and my transgressions demand that His right hand should smite me low. How can I be saved? Were God unjust, He might forgive: but, alas! He is not so, He is severely just. ‘He layeth justice to the line, and righteousness to the plummet.’ He is the judge of all the earth, and He must do right. How then can I escape from His righteous wrath which must be stirred up against me?”…It is true that God is just…let hell’s bottomless lake declare what is the awful vengeance of God against the sins of man. Let the sighs, and groans, and moans, and shrieks of spirits condemned of God, rise in your ears, and bear witness that He is a God who will not spare the guilty, who will not wink at iniquity, transgression, and sin, but who will have vengeance upon every rebel, and will give justice its full satisfaction for every offence.

Wonder ye heavens! be astonished O earth! that very justice which stood in the sinner’s way and prevented his being pardoned, has been by the gospel of Christ appeased; by the rich atonement offered upon Calvary, justice is satisfied, has sheathed its sword, and has now not a word to say against the pardon of the penitent. ~ C.H. Spurgeon

What is man that You are mindful of him, or the son of man that You take care of him? – Hebrews 2:6

Ah! friends, we might have been blotted out of existence, and I do not know that there would have been any lack in God’s universe if the whole race of man had disappeared. That universe is too wide and great to miss such chirping grasshoppers as we are. When one star is blotted out it may make a little difference to our midnight sky, but to an eye that sees immensity it can make no change. Know ye not that this little solar system, which we think so vast, and those distant fixed stars, and yon mighty masses of nebulae, if such they be, and yonder streaming comet, with its stupendous walk of grandeur-all these are only like a little corner in the field of God’s great works? He taketh them all up as nothing, and considereth them mighty as they be, and beyond all human conception great-to be but the small dust of the balance which does not turn the scale; and if they were all gone to-morrow there would be no more loss than as if a few grains of dust were thrown to the summer’s wind.

But God Himself must stoop, rather than we should die. Oh! what magnificence of love! And the more so because there was no need for it. In the course of nature God would have been as holy and as heavenly without us as He is with us, and the pomp of yonder skies would have been as illustrious had we been dashed into the flames of hell as it will be now. God hath gained nought, except the manifestation of a love beyond an angel’s dream; a grace, the heights, and depths, and lengths, and breadths of which surpass all knowledge of all creatures. God only knows the love of God which is manifested in Jesus Christ. ~ C.H. Spurgeon
