Ephesians 5:29-32

For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church: for we are members of his body, of his flesh, and of his bones. For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. This is a great mystery: but I speak concerning Christ and the church.
