23. He went up into a mountain alone. It is probable that the Son of God, who was fully aware of the tempest that was coming on, did not neglect the safety of his disciples in his prayers; and yet we naturally wonder that he did not rather prevent the danger than employ himself in prayer. But in discharging all the parts of his office as Mediator, he showed himself to be God and man, and exhibited proofs of both natures, as opportunities occurred. Though he had all things at his disposal, he showed himself to be a man by praying; and this he did not hypocritically, but manifested sincere and human affection towards us. In this manner his divine majesty was for a time concealed, but was afterwards displayed at the proper time.
In going up into the mountain he consulted his convenience, that he might have more leisure for praying when removed from all noise. We know how easily the slightest interruptions destroy the ardor of prayer, or at least make it languish and cool. Though Christ was in no danger of this fault, yet he intended to warn us by his example, that we ought to be exceedingly careful to avail ourselves of every assistance for setting our minds free from all the snares of the world, that we may look direct towards heaven. Now in this respect solitude has a powerful influence, by disposing those who engage in prayer, when God is their only witness, to be more on their guard, to pour their heart into his bosom, to be more diligent in self-examination; and, in a word—remembering that they have to do with God—to rise above themselves. At the same time, it must be observed, that he did not lay down a fixed rule, as if we were never permitted to pray except in retirement; for Paul enjoins us to pray everywhere, lifting up clean hands, (1 Timothy 2:8;) and Christ himself sometimes prayed in presence of others, and even instructed his disciples to assemble together for offering social prayer. But that permission to pray in all places does not hinder them from engaging in secret prayer at proper seasons.
