The Lord teaches us:
Matthew 22
29Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. 30For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. 31But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, 32I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living. 33And when the multitude heard this, they were astonished at his doctrine
