Romans 14:13, Foster True Peace
We have been given this freedom from the bondage of sin. Let us not abuse this freedom by allowing the flesh to manifest itself Gal. 5:19-21. This word “serve” is a command the believers are to do continually as a habit of life. It means “to do service, to perform services of kindness and Christian love.” [Thayer Lexicon]
To love one another is to treat others like how you would like others to treat you. And to devour describes the scheming heart to get gain by destroying the other person.
