Thoughts for reflection: Why do we have all of the laws that we do in the Old Testament if we aren’t supposed to follow them? This is a hard question to answer. Jesus says that He came not to abolish the laws of what we know as the Old Testament. He gave us the Great Commandment, love God with all you are, and love others as yourself, which should both supersede them and change how we view them. For example, it is one thing to say, you shall not kill. It is something entirely different to say, love others as you love yourself. This difference is what Paul is trying to get them to understand. The law of the Old Testament is not all invalidated, but it is changed because of our faith in Jesus Christ.
What would your behavior look like towards someone if you were told not to kill them, covet their things, lie about them, steal from them, or violate their marriage if they are married? Now, what would your behavior look like towards someone if you were told to love them? Why do you think we tend to celebrate the 10 Commandments much more than we celebrate the Great Commandment, especially in public settings?
