14 and he appointed twelve, that they may be with him, and that he may send them forth to preach, 15 and to have power to heal the sicknesses, and to cast out the demons. 16 And he put on Simon the name Peter; 17 and James of Zebedee, and John the brother of James, and he put on them names—Boanerges, that is, 'Sons of thunder;' 18 and Andrew, and Philip, and Bartholomew, and Matthew, and Thomas, and James of Alpheus, and Thaddeus, and Simon the Cananite, 19 and Judas Iscariot, who did also deliver him up; and they come into a house.
Matthew Henry's Commentary on Mark 3:14-19
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.
