Mark 12:27

He is not the God of the dead, but the God of the living; ye therefore do greatly err.

The question which Jesus uses: Do ye not err on account of this fact?. is stronger than a positive statement as to their wrong belief and argument. He says, in effect: Don't you see how absolutely foolish you are in your belief and in your discussion? The point of your story is based upon a wrong supposition. Two grave facts must be noted against the Sadducees and all that follow them in similar arguments: They do not know the Scriptures; they do not know the power of God. Most of the most rabid and radical enemies of the Bible-truths have never even read the Bible, and yet they presume to judge it in the minutest details. And they have no conception of the great power of God; their finite minds cannot grasp infinity, and yet they make futile attempts to make matters beyond their ken clear to themselves and to others by theories that are subject to change without notice. Marrying and giving in marriage will no longer be practiced in heaven, after the resurrection. All physical needs will then be ended definitely, and all the believers in bliss will be sexless. The terms male and female, husband and wife, will no longer be in use, because there will be no need of them. The loved ones will be in heaven, not in the former relation of blood, but in the closer, happier relation of spirit, in union with Christ the Savior. But Jesus gives the Sadducees a lesson also concerning the resurrection of the dead. Since they rejected all the Old Testament writings but the five books of Moses, He takes His proof from one of these, from Exodus 3:6. In speaking to Moses at the burning bush, God expressly called Himself the God of Abraham, the God of Isaac, the God of Jacob. All of these patriarchs, at this time, had died, and they were presumably dead, so far as men could see and judge. But, Jesus explains to the Sadducees, the fact that God so designates Himself, shows that these men, though dead in body, were yet alive, that their soul, the most essential part of them, was alive. The living God is the God of the living only, His work concerns the living only. This is true of all believers. All, to whom the Lord is God, live unto God, even when they have closed their eyes in temporal death. Death, to them, is only a temporary sleep, in the midst of which God considers them as living. And therefore God will truly awaken all the dead that have fallen asleep in Him to a new and blessed life in all eternity.
