(3.) The death of sin; — sin dying in us now, in some measure, whilst we are alive. This is a third concernment of sin which it is our wisdom to be acquainted with; and it is hid only in Christ. There is a twofold dying of sin:— as to the exercise of it in our mortal members; and as to the root, principle, and power of it in our souls. The first, indeed, may be learned in part out of Christ. Christless men may have sin dying in them, as to the outward exercise of it. Men’s bodies may be disabled for the service of their lusts, or the practice of them may not consist with their interest. Sin is never more alive See Treatise on Mortification. [Works., vol. vi.] than when it is thus dying. But there is a dying of it as to the root, the principle of it, — the daily decaying of the strength, power, and life of it; and this is to be had alone in Christ. Sin is a thing that of itself is not apt to die or to decay, but to get ground, and strength, and life, in the subject wherein it is, to eternity; prevent all its actual eruptions, yet its original enmity against God will still grow. In believers it is still dying and decaying, until it be utterly abolished. The opening of this treasury [mystery?] you have, Rom. vi. 3–6, etc. “Know ye not, that so many of us as were baptised into Jesus Christ were baptised into his death? Therefore we are buried with him by baptism into death, that like as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection; knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.” This is the design of the apostle in the beginning of that chapter, not only to manifest whence is the principle and rise of our mortification and the death of sin, even from the death and blood of Christ; but also the manner of sin’s continuance and dying in us, from the manner of Christ’s dying for sin. He was crucified for us, and thereby sin was crucified in us; he died for us, and the body of sin is destroyed, that we should not serve sin; and as he was raised from the dead, that death should not have dominion over him, so also are we raised from sin, that it should not have dominion over us. This wisdom is hid in Christ only. Moses at his dying day had all his strength and vigour; so have sin and the law to all out of Jesus: at their dying day, sin is no way decayed. Now, next to the receiving of the righteousness prepared for us, to know this is the chiefest part of our wisdom. To be truly acquainted with the principle of the dying of sin, to feel virtue and power flowing from the cross of Christ to that purpose, to find sin crucified in us, as Christ was crucified for us, — this is wisdom indeed, that is in him alone.
