17.Peter was grieved. Peter undoubtedly did not perceive the object which Christ had in view, in putting the same question so frequently; and therefore he thinks that he is-in-directly accused, as if he had not answered with sincerity. But we have already showed that the repetition was not superfluous. Besides, Peter was not yet sufficiently aware how deeply the love of Christ must be engraven on the hearts of those who have to struggle against innumerable difficulties. He afterwards learned by long experience, that such a trial had not been made in vain. Those who are to undertake the charge of governing the Church are also taught, in his person, not to examine themselves slightly, but to make a thorough scrutiny what zeal they possess, that they may not shrink or faint in the middle of their course. We are likewise taught, that we ought patiently and mildly to submit, if at any time the Lord subject us to a severe trial; because he has good reasons for doing so, though they are generally unknown to us.
