14 And He appointed twelve , so that they would be with Him and that He could send them out to preach , 15 and to have authority to cast out the demons . 16 And He appointed the twelve : Simon (to whom He gave the name Peter ), 17 and James , the son of Zebedee , and John the brother of James (to them He gave the name Boanerges , which means , "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 Zealot ; 19 and Judas Iscariot , who betrayed Him.
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.
