5:13-15 The gospel is a doctrine according to godliness, 1Ti 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.
