Jesus said, “That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.” (Matthew 5:28)
The first wife and her children are irreplaceable in God’s family. A son of God will not divorce her and a son of God will not marry a man’s divorced wife. (Matthew 5:32)
Jesus’ rules do not apply to men. Men can do all of this and more with laws and a lawyer.
