Matthew Henry Commentary Galatians 5:13-15

"For ye, brethren, were called for freedom; only [use] not your freedom for an occasion to the flesh, but through love be servants one to another. For the whole law is fulfilled in one word, [even] in this: Thou shalt love thy neighbor as thyself. But if ye bite and devour one another, take heed that ye be not consumed one of another." — Galatians 5:13-15 (ASV)

The gospel is a doctrine according to godliness (1 Timothy 6:3), and is so far from giving the least approval to sin, that it places us under the strongest obligation to avoid and subdue it. The apostle urges that all the law is fulfilled in one word, even in this: Thou shalt love thy neighbour as thyself. If Christians, who should help one another and bring joy to one another, quarrel, what can be expected but that the God of love should deny his grace, that the Spirit of love should depart, and the evil spirit, who seeks their destruction, should prevail? It would be a happy thing if Christians, instead of biting and devouring one another on account of different opinions, would set themselves against sin in themselves and in the places where they live.
