Matthew 8:18

Here is, I. Christ's removing to the other side of the sea of Tiberias, and his ordering his disciples, whose boats attended him, to get their transport-vessels ready, in order to it, Mat 8:18. The influences of this Sun of righteousness were not to be confined to one place, but diffused all the country over; he must go about to do good; the necessities of souls called to him, Come over, and help us (Act 16:9); he removed when he saw great multitudes about him. Though by this it appeared that they were desirous to have him there, he knew there were others as desirous to have him with them, and they must have their share of him: his being acceptable and useful in one place was no objection against, but a reason for, his going to another. Thus he would try the multitudes that were about him, whether their zeal would carry them to follow him, and attend on him, when his preaching was removed to some distance. Many would be glad of such helps, if they could have them at next door, who will not be at the pains to follow them to the other side; and thus Christ shook off those who were less zealous, and the perfect were made manifest. II.
