For Christ also hath once suffered for sins, the just for the unjust, that He might bring us to God, being put to death in the flesh, but quickened by the Spirit… – 1 Peter 3:18

The curse of God is not easily taken away; in fact, there was but one method whereby it could be removed. The lightnings were in God’s hand; they must be launched; He said they must. The sword was unsheathed; it must be satisfied; God vowed it must. How, then, was the sinner to be saved? The only answer was this. The Son of God appears; and He says, “Father! launch Thy thunderbolts at Me; here is My breast-plunge that sword in here; here are My shoulders-let the lash of vengeance fall on them;” and Christ, the Substitute, came forth and stood for us, “the just for the unjust, that He might bring us to God.”

We have heard some preach a gospel, something after this order-that though God is angry with men, yet out of His great mercy, for the sake of something that Christ has done, He does not punish them, but remits the penalty. Now, we hold, that this is not of God’s gospel; for it is neither just to God, nor safe to man. We believe that God never remitted the penalty, that He did not forgive the sin without punishing it, but that there was blood for blood, and stroke for stroke, and death for death, and punishment for punishment, without the abatement of a solitary jot or tittle; that Jesus Christ, the Saviour, did drink the veritable cup of our redemption to its very dregs; that He did suffer beneath the awful crushing wheels of divine vengeance, the self-same pains and sufferings which we ought to have endured. O! the glorious doctrine of substitution! When it is preached fully and rightly, what a charm and what power it hath. ~ C.H. Spurgeon
