13 For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.
English Standard Version
13 For you were called to freedom, brothers. Only do not use your freedom as an opportunity for the flesh, but through love serve one another.
13 It is absolutely clear that God has called you to a free life. Just make sure that you don't use this freedom as an excuse to do whatever you want to do and destroy your freedom. Rather, use your freedom to serve one another in love; that's how freedom grows.
New King James Version
13 For you, brethren, have been called to liberty; only do not use liberty as an opportunity for the flesh, but through love serve one another.
New Living Translation
13 For you have been called to live in freedom, my brothers and sisters. But don't use your freedom to satisfy your sinful nature. Instead, use your freedom to serve one another in love.
The gospel is a doctrine according to godliness, 1 Timothy 6:3, and is so far from giving the least countenance to sin, that it lays 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 rejoice 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? Happy would it be, 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.
5:13In contexts like this, the Greek word for "flesh" ("sarx" ) refers to the sinful state of human beings, often presented as a power in opposition to the Spirit; also in verses 16, 17, 19 and 24; and in 6:8.
