The World to Come

Therefore in the resurrection whose wife shall she be of the seven? for they all had her. Mat 22:28
Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. 
But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living. Mat 22:29-32

THE SCRIPTURES TEACH THE RESURRECTION

​The Sadducees professed themselves to be bound by the Pentateuch, and to have searched in vain for evidences of a life beyond. They were greatly startled, therefore, when our Lord proved human immortality from the book of Exodus. He had never passed through their schools and sat at the feet of their great teachers, but He showed them that “at the Bush” the voice of God attested eternal life.
The great I AM would never have spoken of Himself as the God of the patriarchs, centuries after their earthly career had closed, unless they had been living somewhere still. It was certain that they were all alive; otherwise God would have said, “I was their God.” Death is not a chamber, but a passage; not an abiding-place, but a crossing over; not a state, but an act, an experience, a crossing of the bar, a going within the veil. Abraham, Isaac, Jacob, and all the myriads who have warred and stormed over the earth, are living as intensely as ever. F.B. Meyer  (See also Luke 20:33-38)

There Is No God of the Dead

He is not a God of the dead, or, there is no God of the dead - That is, the term God implies such a relation, as cannot possibly subsist between him and the dead; who in the Sadducees' sense are extinguished spirits; who could neither worship him, nor receive good from him. So that all live to him - All who have him for their God, live to and enjoy him. This sentence is not an argument for what went before; but the proposition which was to be proved. And the consequence is apparently just. For as all the faithful are the children of Abraham, and the Divine promise of being a God to him and his seed is entailed upon them, it implies their continued existence and happiness in a future state as much as Abraham's. And as the body is an essential part of man, it implies both his resurrection and theirs; and so overthrows the entire scheme of the Sadducees doctrine. John Wesley

The Sadducees Silenced

I. GIVE SOME ACCOUNT OF THE SADDUCEES:—A small number of men of rank and affluence, who had shaken off such opinions and practices as they deemed a restraint upon their pleasures. They acknowledged the truth of the Pentateuch, but rejected the tradition of the elders. They also denied a future state, and believed that the soul dies with the body.
II. CONSIDER THE ARGUMENT OF THE SADDUCEES.--the Sadducees, which deny that there is any resurrection; and they came to him, tempting him with a question they were sure he had no answer for.
III. CONSIDER HOW JESUS CHRIST ACTED ON THIS OCCASION.--His answer instantly answered the question of this world, and the world to come-"And Jesus answering said unto them, The children of this world marry, and are given in marriage: But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage: "
1. He removed the difficulty which had puzzled the Sadducees. They had not studied the Scriptures with sufficient attention, and a sincere desire of understanding their meaning. If they had done so, they could not have doubted of a future state. If, again, they had reflected on the power of God, they would have concluded that what might appear difficult or impossible to man, is possible and of easy accomplishment with God. He then explained the difficulty. It is to be observed, however, that He speaks only of the righteous. On this subject our Saviour reveals two important truths,—First, that the righteous never die; and, secondly, that they become like the angels.
2. Our Saviour, then, having removed the difficulty which had embarrassed the Sadducees, and having at the same time communicated new and important information concerning the world of spirits, next proceeded to prove from Scripture the certainty of a future state. He argued from a passage in the Book of Exodus, where God is represented as speaking from the burning bush to Moses, and saying, “ I am the God of Abraham, of Isaac, and of Jacob” (Exo_3:6). It is here particularly to be observed, that the force of our Saviour’s argument rests upon the words, I am the God. Had the words been I was the God, the argument would be destroyed.
IV. ATTEND TO THE INFERENCES WHICH WE MAY JUSTLY DRAW FROM THIS SUBJECT.
1. A difficulty arising from our ignorance is not sufficient to disprove or weaken direct or positive evidence.
2. Although a future state is not clearly revealed in the Books of Moses, yet it is presupposed, for the passage here selected can be explained only on the assurance that there is such a state.
3. From our Saviour’s declaration here, we also obtain the important information, that the righteous, after their removal from this world by death, do not sink into a state of sleep or insensibility; for the passage which He quotes implies that Abraham, Isaac, and Jacob, after death, remained alive, and still continued to acknowledge and serve God; for all these things are included in what our Saviour says. Now, the inference we draw is, that what is true respecting the patriarchs we may safely extend to all good men, that they are all in a similar situation.
4. While informed by our Saviour, in the parable of the rich man and Lazarus, that immediately after death angels are employed to conduct the spirits of the righteous to paradise, we are also assured here by the same authority, that they shall be made like to the angels. When to these we add the passage quoted above, from the Epistle to the Hebrews, respecting the office of angels, it appears necessarily to follow that the righteous shall be elevated in rank and situation; for they shall associate with celestial beings, and consequently will receive all the benefits which can arise from society so pure and exalted. Nor can we help believing that while thus mingled with angels they will be engaged in similar duties and employments. (J. Thompson, D. D.)
