By this shall all men know that you are my disciples, if you have love one to another.
The marks of a true disciple of any master are —
I. BELIEF in his master's words.
II. ATTACHMENT to his master's person.
III. OBEDIENCE to his master's precepts.
IV. IMITATION of his master's example. Obedience and imitation may be summed up in one word — love. If we love Christ we shall believe, obey, and imitate Him; and we must show that love by loving one another.
(J. R. Bailey.)
