John 1:38
“Then Jesus turned, and saw them following, and says unto them, What do you seek?”
Hence we are taught, that God does not prevent our wills by His gifts, but that when we begin, when we provide the being willing, then He gives us many opportunities of salvation. “What do you seek?” How is this? He who knows the hearts of men, who dwells in our thoughts, does He ask? He does; not that He may be informed; how could that be? But that by the question He may make them more familiar, and impart to them greater boldness, and show them that they are worthy to hear Him; for it was probable that they would blush and be afraid, as being unknown to him, and as having heard such accounts of Him from the testimony of their teacher. Therefore to remove all this, their shame and their fear, he questions them, and would not let them come all the way to the house in silence. Yet the event would have been the same had He not questioned them; they would have remained by following Him, and walking in His steps would have reached His dwelling. Why then did He ask? To effect that which I said, to calm their minds, yet disturbed with shame and anxiety, and to give them confidence.
Nor was it by their following only that they showed their earnest desire, but by their question also: for when they had not as yet learned or even heard anything from Him, they call Him, “Master”; thrusting themselves as it were among His disciples, and declaring what was the cause of their following, that they might hear somewhat profitable. Observe their wisdom also. They did not say, “Teach us of Your doctrines, or some other thing that we need to know”; but what? “Where dwellest Thou?” Because, as I before said, they wished in quiet to say somewhat to Him, and to hear somewhat from Him, and to learn. Therefore they did not defer the matter, nor say, “We will come tomorrow by all means, and hear you speak in public”; but showed the great eagerness they had to hear Him, by not being turned back even by the hour, for the sun was already near its setting, (“it was,” says John, “about the tenth hour.”) And therefore Christ does not tell them the marks of His abode, nor its situation, but rather induces them to follow Him by showing them that He had accepted them. For this reason He did not say anything of this kind to them, “It is an unseasonable time now for you to enter into the house, tomorrow you shall hear if you have any wish, return home now”; but converses with them as with friends, and those who had long been with Him.
How then says He in another place, “But the Son of Man has not where to lay His head”, while here He says, “Come and see” where I abide? Because the expression “has not where to lay His head,” signifies that He had no dwelling place of His own, not that He did not abide in a house. And this too is the meaning of the comparison. The Evangelist has mentioned that “they abode with Him that day,” but has not added wherefore, because the reason was plain; for from no other motive did they follow Christ, and He draw them to Him, but only that they might have instruction; and this they enjoyed so abundantly and eagerly even in a single night, that they both proceeded straightway to the capture of others.
4. Let us then also learn hence to consider all things secondary to the hearing the word of God, and to deem no season unseasonable, and, though a man may even have to go into another person's house, and being a person unknown to make himself known to great men, though it be late in the day, or at any time whatever, never to neglect this traffic. Let food and baths and dinners and the other things of this life have their appointed time; but let the teaching of heavenly philosophy have no separate time, let every season belong to it. For Paul says, “In season, out of season, reprove, rebuke, exhort”; and the Prophet too says, “In His law will he meditate day and night”; and Moses commanded the Jews to do this always. For the things of this life, baths, I mean, and dinners, even if they are necessary, yet being continually repeated, render the body feeble; but the teaching of the soul the more it is prolonged, the stronger it renders the soul which receives it. But now we portion out all our time for trifles and unprofitable silly talking, and we sit together idly during the morning and afternoon, midday and evening besides, and we have appointed places for this; but hearing the divine doctrines twice or thrice in the week we become sick, and thoroughly sated. What is the reason? We are in a bad state of soul; its faculty of desiring and reaching after these things we have relaxed altogether. And therefore it is not strong enough to have an appetite for spiritual food. And this among others is a great proof of weakness, not to hunger nor thirst, but to be disinclined to both. Now if this, when it takes place in our bodies, is a sure sign of grievous disease, and productive of weakness, much more is it so in the soul.
