There seems to have been a limitation also in their message. They had themselves been to some extent instructed in regard to the nature of the kingdom, its blessedness, its righteousness, its leading principles and features; but, though they may have begun to get some glimpse of the truth in regard to these great matters, they certainly had not yet made it their own; accordingly they are given, as the substance of their preaching, only the simple announcement, with which the Baptist had begun his ministry, and with which Christ also commenced His: "The kingdom of heaven is at hand." Though there seems to have been a limitation on the teaching side, there was none on the side of healing, for their Lord empowers them to do the very same things for the relief of their suffering fellow-countrymen as they had seen Himself doing. We have already seen how much teaching there was in these signs of the kingdom; and we can well believe that it was far better, considering the stage of advancement the apostles had reached, that reliance should be placed on the light such deeds of mercy would necessarily throw on the nature of the kingdom, than on any exposition which, apart from their Master, they could at that time have been able to give. Above all it is to be clear that the privileges of the kingdom are free to all; its blessings are to be dispensed without money and without price: "Freely ye have received, freely give." How, then, were they to be supported? About this they were to give themselves no concern. They were now to put in practice the great command, "Seek ye first the kingdom of God, and His righteousness," relying on the promise, "all these things shall be added unto you." But in no miraculous way are they to look for the provision of their wants. They are to be maintained by those among whom and for whom they labour. This was to be no burden, but a privilege, reserved for those who were found "worthy" (ver. 11). Nor was it to be divided among as many as possible. They were to stay on with the same person who first received them, as the one whom the Master had chosen for the honour; while, if any refused to recognise it as a privilege, there was to be no weak solicitation, but a dignified withdrawal. The regulations throughout are manifestly intended to keep most vividly before their minds that they went not in their own names, nor on their own strength, nor at their own charges,--that they were ambassadors of a King, clothed with His authority, armed with His power, vested with His rights; so that there is a manifest appropriateness in the solemn words with which this part of the commission closes: "Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city" which rejects you (ver. 15).
