Jesus encouraged no illusions in His servants as to their success. From the beginning they were led to expect that some would receive and some would reject their words. In this rapid preparatory mission, there was no time for long delay anywhere; but for us, it is not wise to conclude that patient effort will fail because first appeals have not succeeded. Much close communion with Jesus, not a little self-suppression, and abundant practical wisdom, are needed to determine the point at which further efforts are vain. No doubt, there is often great waste of strength in trying to impress unimpressible people, or to revive some moribund enterprise; but it is a pardonable weakness to be reluctant to abandon a field. Still it _is_ a weakness, and there come times when the only right thing to do is to 'shake off the dust' of the messenger's feet in token that all connection is ended, and that he is clear from the blood of the rejecters. The awful doom of such is solemnly introduced by 'Verily, I say unto you.' It rests on the plain principle that the measure of light is the measure of criminality, and hence the measure of punishment. The rejecters of Christ among us are as much more guilty than 'that city' as its inhabitants were than the men of Sodom. The first section of this charge properly ends with verse 15, the following verse being a transition to the second part. The Greek puts strong emphasis on 'I.' It is He who sends among wolves, therefore He will protect. A strange thing for a shepherd to do! A strange encouragement for the apostles on the threshold of their work! But the words would often come back to them when beset by the pack with their white teeth gleaming, and their howls filling the night. They are not promised that they will not be torn, but they are assured that, even if they are, the Shepherd wills it, and will not lose one of His flock. What is the Christian defence? Prudence like the serpent's, but not the serpent's craft or malice; harmlessness like the dove's, but not without the other safeguard of 'wisdom.' The combination is a rare one, and the surest way to possess it is to live so close to Jesus that we shall be progressively changed into His likeness. Then our prudence will never degenerate into cunning, nor our simplicity become blindness to dangers. The Christian armour and arms are meek, unconquerable patience, and Christ-likeness, To resist is to be beaten; to endure unretaliating is to be victorious. 'Be not overcome of evil, but overcome evil with good.' THE WIDENED MISSION, ITS PERILS AND DEFENCES
