The spirit indeed is willing and desires bodily death as a gentle sleep. It does not consider it to be death; it knows no such thing as death.
"For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his. We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. For one who has died has been set free from sin. Now if we have died with Christ, we believe that we will also live with him. We know that Christ, being raised from the dead, will never die again; death no longer has dominion over him. For the death he died he died to sin, once for all, but the life he lives he lives to God. So you also must consider yourselves dead to sin and alive to God in Christ Jesus." (Romans 6:5-11)
These words of Paul are an admirable Christian picture of death, representing it not as an awful thing, but as something comforting and pleasant to contemplate. For how could Paul present a more attractive description than when he describes it as stripped of its power and repulsiveness and makes it the medium through which we attain life and joy? What is more desirable than to be freed from sin and the punishment and misery it involves, and to possess a joyful, cheerful heart and conscience? For where there is sin and real death – the sense of sin and God’s wrath – there are such terror and dismay that man feels like rushing through iron walls.
That dreadful death which is called in the Scriptures "the second death" is taken away from the Christian through Christ, and is swallowed up in his life. In place of it there is left a miniature death, a death in which the bitterness is covered up. In it the Christian dies according to the flesh; that is, he passes from unbelief to faith, from the remaining sin to eternal righteousness, from woes and sadness and tribulation to perfect eternal joy. Such a death is sweeter and better than any life on earth. For not all the life and wealth and delight and joy of the world can make man as happy as he will be when he dies with a conscience at peace with God and with the sure faith and comfort of everlasting life. Therefore, truly may this death of the body be said to be only a falling into a sweet and gentle slumber. The body ceases from sin. It no longer hinders or harasses the spirit. It is cleansed and freed from sin and comes forth again in the resurrection clothed with the obedience, joy and life which the spirit imparts.
The only trouble is that the stupid flesh cannot understand this. It is terrified by the mask of death, and imagines that it is still suffering the old death; for it does not understand the spiritual dying unto sin. It judges only by outward appearance. It sees that man perishes, decays under the ground and is consumed. Having only this abominable and hideous mask before its eyes, it is afraid of death. But its fear is only because of its lack of understanding. If it knew, it would by no means be afraid or shudder at death. Our reason is like a little child who has become frightened by a bugbear or a mask, and cannot be lulled to sleep; or like a poor man, bereft of his senses, who imagines when brought to his couch that he is being put into the water and drowned. What we do not understand we cannot intelligently deal with. If, for instance, a man has a penny and imagines it to be a five-dollar gold piece, he is just as proud of it as if it were a real gold piece; if he loses it he is as grieved as if he had lost that more valuable coin. But it does not follow that he has suffered such loss; he has simply deluded himself with a false idea.
Thus it is not the reality of death and burial that terrifies; the terror lies in the flesh and blood, which cannot understand that death and the grave mean nothing more than that God lays us – like a little child is laid in a cradle or an easy bed – where we shall sweetly sleep till the judgment day. Flesh and blood shudders in fear at that which gives no reason for it, and finds comfort and joy in that which really gives no comfort or joy. Thus Christians must be harassed by their ignorant and insane flesh, because it will not understand its own good or harm. They must verily fight against it as long as they live, at the cost of much pain and weariness.
There is none so perfect that he does not flee from and shudder at death and the grave. Paul complains and confesses of himself, and in his own person of all Christians: “For that which I do I know not: for not what I would, that do I practice.” (Romans 7:15). In other words: By the spirit, I am well aware that when this body comes to die God simply lays me to rest in sweetest slumber, and I would gladly have my flesh to understand this; but I cannot bring it to it. The spirit indeed is willing and desires bodily death as a gentle sleep. It does not consider it to be death; it knows no such thing as death. It knows that it is freed from sin and that where there is no sin there is no death – life only. But the flesh halts and hesitates, and is in constant dread lest I die and perish in the abyss. It will not allow itself to be tamed and brought into that obedience and into that consoling view of death which the spirit exercises. Even Saint Paul cries out in anxiety of spirit: “Wretched man that I am! who shall deliver me out of the body of this death?” (Romans 7:24).
When we die – spiritually unto sin, and physically to the world and self – what does it profit us? Is there nothing else in store for the Christian but to die and be buried.? By all means yes, he says; we are sure by faith that we also shall live, even as Christ rose from death and the grave and lives. For we have died with him, or, as stated above, “we have become united with him in the likeness of his death.” By his death he has destroyed our sin and death; therefore, we share in his resurrection and life. There shall be no more sin and death in our spirit or body, just as there is no more death in him. Christ, having once died and been raised again, dies no more. There is nothing to die for. He has accomplished everything. He has destroyed the sin for which he died, and has swallowed up death in victory. And that he now lives means that he lives in everlasting righteousness, life and majesty. So, when you have once passed through both deaths, the spiritual death unto sin and the gentle death of the body, death can no more touch you, no more reign over you.
