Matthew 22:29

How wrong you are! Their basic error was to say that there were no such things as spirits. So they rejected the idea of a special spiritual creation such as angels. But if man is a spirit who survives death, then the God who created him so that a "body" is necessary to his activity and happiness, would in some way restore a body to him after death. The Bible strongly teaches a "rising from death." See 1 Corinthians 15:35-49. It is because you don't know. The Scriptures proved them wrong. Jesus uses the first five books of the Old Testament [which they did believe] to prove that man is a spirit who survives death. This proves the "raising from death."
