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.He ordained twelve - The word rendered "ordained" here does not express our notion of ordination to the ministry. It means, literally, "he made" - that is, he "appointed" twelve to be with him.

Twelve - The reason why "twelve" were chosen was, probably, that such a number would be deemed competent witnesses of what they saw; that they could not be easily charged with being excited by sympathy, or being deluded, as a multitude might; and that, being destined to go into all the world, a considerable number seemed indispensable. Perhaps, also, there was some reference to the fact that "twelve" was the number of the twelve tribes of Israel.
