The Sadducees, who did not believe that a dead person could be raised to life, were trying to trap Jesus about the resurrection (Luke 20:27-40). The Lord used their question as an opportunity to teach about the nature of eternal life. Showing that He fully honoured the text of the Old Testament as God's revelation, Jesus referred to Exodus 3:14-15 when God spoke to Moses at the burning bush. When Moses asked God to reveal His Name, He identified Himself as the ever-present one, "I AM who I AM". He also described His relationship to Abraham, Isaac and Jacob in the present tense.
