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.

People's New Testament

22:32 I am the God of Abraham. See Ex 3:6. God does not say, I was, but I 'am' the God of Abraham, and of Isaac, and of Jacob. The present tense shows that he is still the God of the departed patriarchs, and that they are still in existence.

God is not the God of the dead, but of the living. Queen Victoria is not the queen of Bacon, Shakespeare and Ben Jonson, but only of her living subjects. The Savior teaches that the soul is resurrected when it leaves the body, and that there is no unconscious state between death and the final resurrection of the body.

Wesley's Notes

22:32 I am the God of Abraham - The argument runs thus: God is not the God of the dead, but of the living: (for that expression, Thy God, implies both benefit from God to man, and duty from man to God) but he is the God of Abraham, Isaac, and Jacob: therefore, Abraham, Isaac, and Jacob are not dead, but living. Therefore, the soul does not die with the body. So indeed the Sadducees supposed, and it was on this ground that they denied the resurrection. Exod 3:6.

Matthew Henry's Concise Commentary

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!
