10:5-15 The Gentiles must not have the gospel brought them, till the Jews have refused it. This restraint on the apostles was only in their first mission. Wherever they went they must proclaim, The kingdom of heaven is at hand. They preached, to establish the faith; the kingdom, to animate the hope; of heaven, to inspire the love of heavenly things, and the contempt of earthly; which is at hand, that men may prepare for it without delay. Christ gave power to work miracles for the confirming of their doctrine. This is not necessary now that the kingdom of God is come. It showed that the intent of the doctrine they preached, was to heal sick souls, and to raise those that were dead in sin. In proclaiming the gospel of free grace for the healing and saving of men's souls, we must above all avoid the appearance of the spirit of an hireling. They are directed what to do in strange towns and cities. The servant of Christ is the ambassador of peace to whatever place he is sent. His message is even to the vilest sinners, yet it behoves him to find out the best persons in every place. It becomes us to pray heartily for all, and to conduct ourselves courteously to all. They are directed how to act as to those that refused them. The whole counsel of God must be declared, and those who will not attend to the gracious message, must be shown that their state is dangerous. This should be seriously laid to heart by all that hear the gospel, lest their privileges only serve to increase their condemnation.
12. And when ye come into an house—or "the house," but it means not the worthy house, but the house ye first enter, to try if it be worthy.
salute it—show it the usual civilities.
