Serve One Another In Love

Galatians 5:13-15

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. 
14  For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself. 
15  But if ye bite and devour one another, take heed that ye be not consumed one of another.
