1. You are in error because you do not know the power of God, or
You are in error because you do not know the scriptures
2. Sadducees did not believe in resurrection
3. Sadducees gave him an example concerning the physical
resurrection of the dead, 7 brothers married to 1 woman.
4. Sadducees, who did not believe in resurrection, asked Jesus whose wife she will be upon resurrection
5. He confirms resurrection
He denies the resurrection to involve marriage
30At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven
6. He denies that they are dead to God. When He told Moses (after the physical deaths of Abraham, Isaac and Jacob) that "I am the God of Abraham, the God of Isaac and the God of Jacob" He was confirming that to God - Abraham, Isaac and Jacob were still living, not dead. Their physical bodies had long returned to the dust, but they themselves still lived.

We see this in the example and why Moses commanded that a brother of a dead man was to marry the widow and raise up children for his dead brother. The woman spiritually was one with the dead husband, and therefore any children born to the brother are still the dead brothers lineage. In this manner, as the author of creation, every person living in the 'mind' of God comes into this world. Just because one brother dies does not mean that his descendants do not come forth into the world. They do.

God is a God of the Living because like Abraham, Isaac and Jacob, at the time of Moses, long after their physical death, they still are living. He is still their God. And they will receive a new body, what that will be we do not know, but just as we see that Jesus showed a body after resurrection which was somehow different, those too in Christ will receive such.
