Mark 6:33

So do thou not wait for Christ till He Himself call you, but outrun Him, and come before Him.

(ubi sup.) How arose the necessity for giving rest to His disciples, He shows, when He adds, For there were many coming and going, and they had no leisure so much as to eat; we may then see how great was the happiness of that time, both from the toil of the teachers, and from the diligence of the learners. It goes on, And embarking in a ship, they departed into a desert place privately. The disciples did not enter into the ship alone, but taking up the Lord with them, they went to a desert place, as Matthew shows. (Matt. 14) Here He tries the faith of the multitude, and by seeking a desert place He would see whether they care to follow Him. And they follow Him, and that not on horseback, nor in carriages, but laboriously coming on foot, they show how great is their anxiety for their salvation. There follows, And the people saw them departing, and many knew him, and ran afoot thither out of all cities, and outwent them. In saying that they outwent them on foot, it is proved that the disciples with the Lord did not reach the other bank of the sea, or of the Jordan, but they went to the nearest places of the same country, where the people of those parts could come to them on foot.

(in Marc. 2, 26) But when Christ goes to the deserts of the Gentiles, many bauds of the faithful leaving the walls of their cities, that is their old manner of living, follow Him.
