You shall not commit adultery.
Exodus 20:14
Adultery. When you think about it, it seems pretty common place nowadays. It seems like every time you turn around you are hearing about someone 
cheating on their spouse. Their problems didn’t begin when one spouse cheated on the other. Adultery is the end product of a matter of the heart.
Jesus, in His sermon on the mount, says that “everyone who looks at a woman with lust for her has already committed adultery with her in his heart.” (Matthew 5:28)
How can this be? Look but don’t touch, right? Wrong.
Here’s the deal. Adultery is infidelity; infidelity is unfaithfulness and disloyalty. When you look at a woman (or man) are you being faithful of loyal to your spouse? Probably not.
In Proverbs 4:23 God tells us to guard our hearts because it determines the course of our lives. (NLT) Another translation says that the heart “affects everything that you do.” If you’ve been around for awhile then you’ve probably heard me say that the heart is the seat of our mind, will, and emotions. This is why our heart affects all that we do because what we think, what we desire, and what we feel determine our choices.
When we lust we long for something. In the case of people, we long for someone that is not our spouse. We focus our thoughts on someone who is not our spouse. We desire someone who is not our spouse. We have feelings for someone who is not our spouse. This is why Jesus said that when we lust, we have already committed adultery.
Guard your heart.
Be faithful.
