What is God’s definition of adultery? - Adultery - TouchPoints

Hebrews 13:4Give honor to marriage, and remain faithful to one another in marriage. God will surely judge people who are immoral and those who commit adultery.

Adultery is being unfaithful to the person we have married. In general, this involves forming a sexual relationship with someone other than our spouse. But even an intimate emotional relationship with another, or unfaithful thoughts about someone, can become adulterous if they take us away from the one we’ve married. Similarly, in the spiritual realm, we commit adultery against God when we are unfaithful to him by loving anything or anyone more than him or by worshiping anything or anyone except him.

Mark 10:11He told them, “Whoever divorces his wife and marries someone else commits adultery against her.”

The commitment to remain faithful “till death do us part” is a serious commitment and should not be taken lightly. Breaking the marriage vow and joining with another is adultery.

Proverbs 4:23Guard your heart above all else, for it determines the course of your life.

Matthew 5:28“But I say, anyone who even looks at a woman with lust has already committed adultery with her in his heart.”

Our actions flow from our hearts. That is why Jesus has such careful instructions for what desires we allow ourselves to dwell on. He clearly states when we look at another person with lust, we are being unfaithful to our spouse. This command is given both to protect our relationship with our spouse and our relationship with God.
