13 And he goeth up into the mountain, and calleth unto him whom he himself would; and they went unto him. 14 And he appointed twelve, that they might be with him, and that he might send them forth to preach, 15 and to have authority to cast out demons: 16 and Simon he surnamed Peter; 17 and James the [son] of Zebedee, and John the brother of James; and them he surnamed Boanerges, which is, Sons of thunder: 18 and Andrew, and Philip, and Bartholomew, and Matthew, and Thomas, and James the [son] of Alphaeus, and Thaddaeus, and Simon the Cananaean, 19 and Judas Iscariot, who also betrayed him. And he cometh into a house.
20 And the multitude cometh together again, so that they could not so much as eat bread. 21 And when his friends heard it, they went out to lay hold on him: for they said, He is beside himself.

Commentary on Mark 3:13-21
(Read Mark 3:13-21)
Christ calls whom he will; for his grace is his own. He had called the apostles to separate themselves from the crowd, and they came unto him. He now gave them power to heal sicknesses, and to cast out devils. May the Lord send forth more and more of those who have been with him, and have learned of him to preach his gospel, to be instruments in his blessed work. Those whose hearts are enlarged in the work of God, can easily bear with what is inconvenient to themselves, and will rather lose a meal than an opportunity of doing good. Those who go on with zeal in the work of God, must expect hinderances, both from the hatred of enemies, and mistaken affections of friends, and need to guard against both.
