So long as God gives Him access to the people, He continues His labour of love. Nevertheless, He was conscious of the iniquity that governed the people, although He did not seek His own glory. Having exhorted His disciples to pray that labourers might be sent into the harvest, He begins (chap. 10) to act in accordance with that desire. He calls His twelve disciples, He gives them power to cast out devils and to heal the sick, and He sends them to the lost sheep of the house of Israel. We see, in this mission, how much the ways of God with Israel form the subject of this Gospel. They were to announce to that people, and to them exclusively, the nearness of the kingdom, exercising at the same time the power they had received: a striking testimony to Him who was come, and who could not only work miracles Himself, but confer power on others to do so likewise. He gave them authority over evil spirits for this purpose. It is this which characterises the kingdom-man healed of all sickness and the devil cast out Accordingly, in Hebrews 6, miracles are called "the powers of the world to come." 
They were also, with respect to their need, to depend entirely on Him who sent them. Emmanuel was there. If miracles were a proof to the world of their Master's power, the fact that they lacked nothing should be so to their own hearts The ordinance was abrogated during that period of their ministry which followed the departure of Jesus from this world (Luke 22:35-37). That which He here (Matt. 10) commands His disciples appertains to His presence as Messiah, as Jehovah Himself, on the earth. Therefore the reception of His messengers, or their rejection, decided the fate of those to whom they were sent. In rejecting them they rejected the Lord Emmanuel, God with His people.  But, in fact, He sent them forth as sheep in the midst of wolves. They would need the wisdom of serpents, and were to exhibit the harmlessness of doves (rare union of virtues, found only in those who, by the Spirit of the Lord, are wise unto that which is good and simple concerning evil).
If they did not beware of men (sad testimony as to these), they would but suffer; but when scourged and brought before councils and governors and kings, all this should become a testimony unto them-a divine means of presenting the gospel of the kingdom to kings and princes, without altering its character or accommodating it to the world, or mixing up the Lord's people with its usages and its false greatness. Moreover circumstances like these made their testimony much more conspicuous than association with the great ones of the earth would have done.
And, to accomplish this, they should receive such power and guidance from the Spirit of their Father as would cause the words they spoke to be not their own words, but His who inspired them. Here, again, their relation with their Father, which so distinctly characterises the sermon on the Mount, is made the basis of their capacity for the service they had to perform. We must remember that this testimony was addressed to Israel only; only that, Israel being under the yoke of the Gentiles since the time of Nebuchadnezzar, the testimony would reach their rulers.
But this testimony would excite an opposition that should break all family ties, and awaken a hatred that would not spare the life of those who had been the most beloved. He who in spite of all this should endure to the end should be saved. Nevertheless the case was urgent. They were not to resist, but if the opposition took the form of persecution, they were to flee and preach the Gospel elsewhere, for before they had gone over the cities of Israel the Son of man should come.  They were to proclaim the kingdom. Jehovah, Emmanuel, was there, in the midst of His people, and the heads of the people had called the master of the house Beelzebub. This had not stopped His testimony, but it very strongly characterised the circumstances in which this testimony was to be rendered He sent them forth, warning them of this state of things, to maintain this final testimony among His beloved people as long as possible. This took place at that time, and it is possible, if circumstances permit, to carry it on until the Son of man comes to execute judgment. Then the master of the house will nave risen up to shut the door. The "to-day" of Psalm 95 will be over. Israel in possession of their cities being the object of this testimony, it is necessarily suspended when they are no longer in their land. The testimony to the future kingdom given in Israel by the apostles after the Lord's death, is an accomplishment of this mission, so far as this testimony was rendered in the land of Israel; for the kingdom might be proclaimed as to be established while Emmanuel was on the earth; or this might be by Christ's returning from heaven as announced by Peter in Acts 3. And this might take place if Israel were in the land, even until Christ should return. Thus the testimony may be resumed in Israel, whenever they are again in their land and the requisite spiritual power is sent forth by God.
Meanwhile, the disciples were to share in Christ's own position. If they called the master of the house Beelzebub, much more they of His household. But they were not to fear It was the necessary portion of those who were for God in the midst of the people. But there was nothing hid that should not be revealed. They themselves were to hold nothing back, but were to proclaim on the housetops all that they had been taught; for everything should be brought into the light; their faithfulness to God in this respect, as well as all other things. This, while it met the secret plottings of their enemies, was itself to characterise the ways of the disciples. God, who is light, and sees in darkness as in light, would bring all out into the light, but they were to do this morally now. Therefore were they to fear nothing while performing this work, unless it were God Himself, the righteous Judge at the last day. Moreover the hairs of their heads were numbered. They were precious to their Father, who took notice of even a sparrow's death. This could not happen without Him who was their Father.
Finally, they were to be thoroughly imbued with the conviction that the Lord was not come to send peace on the earth; no, it should be division, even in the bosom of families. But Christ was to be more precious than father or mother, and even than a man's own life. He who would save his life at the expense of his testimony to Christ should lose it; he who would lose it for the sake of Christ should gain it. He also who should receive this testimony, in the person of the disciples, received Christ, and, in Christ, Him that sent Him. God, therefore, being thus acknowledged in the person of His witnesses on earth, would bestow, on whoever received the latter, a reward according to the testimony rendered. In thus acknowledging the testimony of the rejected Lord, were it only by a cup of cold water, he who gave it should not lose his reward. In an opposing world, he who believes the testimony of God, and receives (in spite of the world) the man who bears this testimony, really confesses God, as well as His servant. It is all that we can do. The rejection of Christ made Him a test, a touchstone.
