And Pharisees came up and in order to test him asked, “Is it lawful for a man to divorce his wife?” He answered them, “What did Moses command you?” They said, “Moses allowed a man to write a certificate of divorce and to send her away.” And Jesus said to them, “Because of your hardness of heart he wrote you this commandment.
The phrase "Because of your hardness of heart" speaks volumes of why there are so many laws in the Old Testament and why God said of New Testament believers, twice in the epistle to the Hebrews, "I will put my laws on their hearts, and write them on their minds". It reminds me of how the bible does not speak against every sin that a person can commit. In truth, laws cannot not keep you from sinning because they only address the externals.
It is why James puts it this way: "whoever knows the right thing to do and fails to do it, for him it is sin". A person with a hard heart will always seek an excuse and a rationalization for their bad behavior - divorce courts are filled with such people. Yet there is a remnant who hear God's voice in their heart and reject the temptation to act in an immoral manner. These are those who walk in kingdom freedom as they trust the Lord with all of their heart.
Help me Lord to trust you, and walk in freedom, with all of my heart today.
