"You have heard that it was said to those of old, 'YOU SHALL NOT COMMIT ADULTERY.' But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart. If your right eye causes you to sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. And if your right hand causes you to sin, cut it off and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
Matthew 5:27-30
Lastly for this section of the Sermon on the Mount, I want to share something I heard earlier this week on Al Mohler’s podcast, “The Briefing.” There is a difference between what is illegal and what is sinful.
Legality is about actions. Sin is likewise about actions, but sin is also about the thoughts, desires, and intentions of our hearts and minds.
Just because something is legal, it may still be sinful. Many, maybe even most, people think if the government decriminalizes, or even legalizes and subsidizes something, it must not be sinful. Incorrect! Many things that are legal are grossly sinful in God’s eyes. If you need examples, how about prostitution, the recreational use of mind-altering drugs, and at the top of the heap: abortion? Sadder still, the fact that society buys the lie that if it is legal it must not be sinful—I shudder to think of how many Christians accept the same lie.
The law cannot (and must not) criminalize thoughts. To do so is a serious overreach because we cannot, and neither can the state, know our minds accurately. But God can, and does (Jeremiah 17:9-10). So, while we should not have to fear the state when it comes to our thoughts, we do well to fear God who knows our every thought, even before think them!
Human laws are important, but they are incomplete and unable to create a truly righteous person or body of people. While human laws cannot accurately judge our hearts, neither can they change people’s hearts. Even God’s revealed written law cannot change hearts. God’s law was never intended to save or change hearts (Romans 3:20, Galatians 2:16). It only exposes our desperate need for a Savior, Jesus (Galatians 3:24). It is only as we are born again, and given new hearts and affections for the things of the Lord, that anyone is saved and has a true desire to obey both the letter and the spirit God’s law.
