NOTES for Luk 20:27-21:4
The Lord points the Sadducees and scribes to the foundation for faith in the resurrection in the Book of Exodus: when God reveals Himself to Moses, He speaks not simply of the "continuity of tradition" from Abraham, Isaac, and Jacob, but of the fact that faith, a person's bond with God, becomes the pledge of that person's eternal life. The idea of the soul's eternal existence in a spiritual world is foreign to Scripture; the continuation of life after death means bodily resurrection from the dead. This means that all who have ever found faith in God are alive, for He is not the God of the dead, but of the living.
