Although you are free from having to obey Jewish rules, instead of doing what your self-directed nature desires, love and serve each other.

Galatians 5:13-15

13 My fellow believers, God chose you in order that you might live without having to obey rules and rituals. But do not assume that because you are free from having to obey rules and rituals, God permits you to do whatever your self-directed nature desires. Instead, constantly, as you love each other, serve each other. 14 Keep in mind that we can sum up all of the laws that God has given us in one law, which is: “You must love each person you come in contact with, just like you love yourself.” 15 Since you are attacking and injuring [MET] each other by the things that you say [MET], I warn you that if you continue doing that, you will totally ruin each other spiritually.
