Theophylact of Ohrid

See then how Christ is free from love of glory; so that the crowd would not press around Him, He calls for a boat, in order to be at a distance from the crowd in it. Consider, finally, that Jesus commands His disciples to have a boat ready, so that the crowd would not press upon Him. Jesus is the word within us, commanding that our boat, that is, our body, be ready for Him, and not be given over to the storm of worldly affairs, so that these crowds of worldly cares would not trouble Christ who dwells within us.
