QUESTION: What is Paul saying in Hebrews 13:4? When is marriage honorable and the bed undefiled?
ANSWER: Paul is simply stating that marriage is honorable and the bed undefiled in the case of all men everywhere! Sexual activity outside the bond of marriage is dishonorable in the case of all men everywhere! Marriage is honorable and the bed undefiled when one man and one women have been joined together by God (Genesis 2:24; Matthew 19:5-6), i.e., when two are married in accordance with the will of God. All other marriages are sinful and dishonorable!
