Mark 10:4
Notice the little word here, suffered. It means that Moses allowed for a bill of divorce, but it was not a primary commandment. The Pharisees understood that, ideally, the marriage bond was not to be broken.
There was actually quite a bit of debate over what constituted a good enough reason to do this. This same kind of debate can be found among Christians today. Is divorce allowed in some circumstances? If so, what is a good reason? These kinds of questions always tend to crop up with laws that are so important to our daily lives. They become hotly debated.
Heavenly Father, thank you for your precepts. May we love all of them, regardless of how much they intersect with our lifestyle. We must give you the glory, for your law is perfect. You have made the right way clear, and we will do well to find it. Thank you for always being at work in our lives. In the name of the Lord Jesus Christ I pray and praise you, Amen.
