and Jesus replies, ‘You are wrong because you do not know the Scriptures and the power of God'. At this point, Jesus uses the Pentateuch (The book of Genesis, Exodus, leviticus, Numbers, and Deuteronomy) as the first five books of the Bible that Sadducees trusted, to show that God is ‘not the God of the dead but of the living'.
He does this by quoting God’s words to Moses at the burning bush in Exodus 3:6: ‘I am the God of Abraham, Isaac, and Jacob’ (Matthew 22:32a).
When Moses heard those words, Abraham, Isaac and Jacob had been dead for hundreds of years, but God did NOT say ‘I was their God’ but ‘I am their God'. It refers to His existence as a living God through the life of Abraham, Isaac, and Jacob.
