Christ set us free from the law of sin and death and we are “not [to] submit again to a yoke of slavery.” (Galatians 5:1) Since we have died to the world in and through Christ, Paul wonders why we “submit to regulations” of the world as if we were still alive to the world. (Colossians 2:20) “For [we] are called to freedom, brothers, only [we are] not [to] use [our] freedom as an opportunity for the flesh, but through love [we are to] serve one another.” (Galatians 5:13) In love, we serve one another and so fulfill “the whole law.” (Galatians 5:14)
In our efforts to conform to regulations which “indeed have an appearance of wisdom in promoting self-made religion and asceticism and severity to the body, but have no value in stopping the indulgence of the flesh” (Colossians 2:23); sometimes we attack one another. “But if [we] bite and devour one another, watch out that [we] are not consumed by one another.” Instead, we are called to “bear one another’s burdens, and so fulfill the law of Christ.” (Galatians 6:2) “As we have opportunity, let us do good to everyone, and especially to those who are of the household of faith.” (Galatians 6:10) Notice Paul calls us to “do good to everyone.”
“Therefore, be imitators of God, as beloved children. And walk in love, as Christ loved us and gave Himself up for us.” (Ephesians 5:1-2)
