29 Jesus replied, "Your mistake is that you don't know the Scriptures, and you don't know the power of God. 30 For when the dead rise, they will neither marry nor be given in marriage. In this respect they will be like the angels in heaven. 31 "But now, as to whether there will be a resurrection of the dead-haven't you ever read about this in the Scriptures? Long after Abraham, Isaac, and Jacob had died, God said, 32 'I am the God of Abraham, the God of Isaac, and the God of Jacob.' So he is the God of the living, not the dead."

Commentary on Matthew 22:23-33
(Read Matthew 22:23-33)
The doctrines of Christ displeased the infidel Sadducees, as well as the Pharisees and Herodians. He carried the great truths of the resurrection and a future state, further than they had yet been reveled. There is no arguing from the state of things in this world, as to what will take place hereafter. Let truth be set in a clear light, and it appears in full strength. Having thus silenced them, our Lord proceeded to show the truth of the doctrine of the resurrection from the books of Moses. God declared to Moses that he was the God of the patriarchs, who had died long before; this shows that they were then in a state of being, capable of enjoying his favour, and proves that the doctrine of the resurrection is clearly taught in the Old Testament as well as in the New. But this doctrine was kept for a more full revelation, after the resurrection of Christ, who was the first-fruits of them that slept. All errors arise from not knowing the Scriptures and the power of God. In this world death takes away one after another, and so ends all earthly hopes, joys, sorrows, and connexions. How wretched are those who look for nothing better beyond the grave!
