Matt. VII. 21.
“Not every one that says unto me, Lord, Lord, shall enter into the kingdom of Heaven, but he that does the will of my Father which is in Heaven.”
Wherefore said He not, “but he that does my will?” Because for the time it was a great gain for them to receive even this first; yea it was very great, considering their weakness. And moreover He intimated the one also by the other. And withal this may be mentioned, that in fact there is no other will of the Son besides that of the Father.
And here He seems to me to be censuring the Jews chiefly, laying as they did the whole stress upon the doctrines, and taking no care of practice. For which Paul also blames them, saying, “Behold you are called a Jew, and restest in the law, and makest your boast of God, and know His will:” “Who then are these men?” you ask. Many of them that believed received gifts such as he that was casting out devils, and was not with Him; such as Judas; for even he too, wicked as he was, had a gift. And in the Old Testament also this may be found, in that grace has oftentimes wrought upon unworthy persons, that it might do good to others. That is, since all men were not meet for all things, but some were of a pure life, not having so great faith, and others just the contrary; by these sayings, while He urges the one to show forth much faith, the others too He was summoning by this His unspeakable gift to become better men. Wherefore also with great abundance did He bestow that grace. For “we wrought,” it is said, “many mighty works.” But “then will I profess unto them, I knew you not.” For “now indeed they suppose they are my friends; but then shall they know, that not as to friends did I give to them.”
And why marvel if He has bestowed gifts on men that have believed on Him, though without life suitable to their faith, when even on those who have fallen from both these, He is unquestionably found working? For so Balaam was an alien both from faith and from a truly good life; nevertheless grace wrought on him for the service of other men. And Pharaoh too was of the same sort: yet for all that even to him He signified the things to come. And Nebuchadnezzar was very full of iniquity; yet to him again He revealed what was to follow after many generations. And again to the son of this last, though surpassing his father in iniquity, He signified the things to come, ordering a marvellous and great dispensation. Accordingly because then also the beginnings of the gospel were taking place, and it was requisite that the manifestation of its power should be abundant, many even of the unworthy used to receive gifts. Howbeit, from those miracles no gain accrued to them; rather they are the more punished. Wherefore unto them did He utter even that fearful saying, “I never knew you:” there being many for whom His hatred begins already even here; whom He turns away from, even before the judgment.
Let us fear therefore, beloved; and let us take great heed to our life, neither let us account ourselves worse off, in that we do not work miracles now. For that will never be any advantage to us, as neither any disadvantage in our not working them, if we take heed to all virtue. Because for the miracles we ourselves are debtors, but for our life and our doings we have God our debtor.
3. Having now, you see, finished all, having discoursed accurately of all virtue, and pointed out the pretenders to it, of various kinds, both such as for display fast and make prayers, and such as come in the sheep's hide; and them too that spoil it, whom He also called swine and dogs: He proceeds to signify how great is the profit of virtue even here, and how great the mischief of wickedness, by saying,
“Whosoever therefore hears these sayings of mine, and does them, shall be likened unto a wise man.”
As thus: What they shall suffer who do not (although they work miracles), you have heard; but you should know also what such as obey all these sayings shall enjoy; not in the world to come only, but even here. “For whosoever,” says He, “hears these sayings of mine, and does them, shall be likened to a wise man.”
Do you see how He varies His discourse; at one time saying, “Not every one that says unto me, Lord, Lord,” and revealing Himself; at another time, “He that does the will of my Father;” and again, bringing in Himself as judge, “For many will say to me in that day, Lord, Lord, have we not prophesied in your name, and I will say, I know you not.” And here again He indicates Himself to have the power over all, this being why He said, “Whosoever hears these sayings of mine.”
Thus whereas all His discourse had been touching the future; of a kingdom, and an unspeakable reward and consolation, and the like; His will is, out of things here also to give them their fruits, and to signify how great is the strength of virtue even in the present life. What then is this her strength? To live in safety, to be easily subdued by no terror, to stand superior to all that despitefully use us. To this what can be equal? For this, not even he that wears the diadem can provide for himself, but that man who follows after virtue. For he alone is possessed of it in full abundance: in the ebb and flow of the things present he enjoys a great calm. The truly marvellous thing being this, that not in fair weather, but when the storm is vehement, and the turmoil great, and the temptations continual, he cannot be shaken ever so little.
“For the rain descended,” says He, “the floods came, the winds blew, and beat upon that house; and it fell not: for it was founded upon the rock.”
By “rain” here, and “floods,” and “winds,” He is expressing metaphorically the calamities and afflictions that befall men; such as false accusations, plots, bereavements, deaths, loss of friends, vexations from strangers, all the ills in our life that any one could mention. “But to none of these,” says He, “does such a soul give way; and the cause is, it is founded on the rock.” He calls the steadfastness of His doctrine a rock; because in truth His commands are stronger than any rock, setting one above all the waves of human affairs. For he who keeps these things strictly, will not have the advantage of men only when they are vexing him, but even of the very devils plotting against him. And that it is not vain boasting so to speak, Job is our witness, who received all the assaults of the devil, and stood unmoveable; and the apostles too are our witnesses, for that when the waves of the whole world were beating against them, when both nations and princes, both their own people and strangers, both the evil spirits, and the devil, and every engine was set in motion, they stood firmer than a rock, and dispersed it all.
And now, what can be happier than this kind of life? For this, not wealth, not strength of body, not glory, not power, nor ought else will be able to secure, but only the possession of virtue. For there is not, nay there is not another life we may find free from all evils, but this alone. And you are witnesses, who know the plots in king's courts, the turmoils and the troubles in the houses of the rich. But there was not among the apostles any such thing.
What then? Did no such thing befall them? Did they suffer no evil at any man's hand? Nay, the marvel is this above all things, that they were indeed the object of many plots, and many storms burst upon them, but their soul was not overset by them, nor thrown into despair, but with naked bodies they wrestled, prevailed, and triumphed.
