You have not chosen me, but I have chosen you, and ordained you, that you should go and bring forth fruit, and that your fruit should remain: that whatsoever you shall ask of the Father in my name, he may give it to you.
All Commentaries on John 15:16 Go To John 15
Cyril of Alexandria
AD 444
His aim is neither to depress His holy disciples by words too grievous, being aware, as God, of the great tendency of human reason to weakness, nor again does He permit them by immoderate assurances to fall into a state of backsliding, for this is indeed a disease and a serious one. But forming a mean between these two from a mixture of both, He fitly leads them into a safe path, and works in them a knowledge of the more stable state and of the complete uncertainty of that which is removed from it.
When therefore, then, he has abundantly comforted them with the words of consolation, and with respect to those things at which they would be likely to be cast down, persuading them in turn to rejoice, He again incites them by His injunctions to diligence to a confident courage; persuading them to change their minds and rather to rejoice at those things at which they had not without reason been dismayed, and charges them to display the utmost zeal, and put into practice an overflowing measure of brotherly love, and to benefit those as yet without faith, and to hasten by the words and deeds that make for righteousness to draw those who are astray to a willingness to be united to God by faith.
Offering Himself then as an Image and Pattern of that which must be done, and bringing before them that which has been already accomplished by Him in their behalf, He persuades them to imitate their Teacher and themselves to be conspicuous in like righteousness when He says: Ye did not choose Me, but I chose you, and what follows.
Conceive Him then as saying: "Gird yourselves with love towards one another, O My disciples; for ye ought indeed yourselves also to devise and do towards one another, and perform with an eager zeal, those things which I have first accomplished towards you. For I chose you, and it is not you that have chosen Me. I drew you to Myself and made Myself known to those who knew Me not through My exceeding kindness, and I brought you into a steadfast opinion so as to lead you up, that is, to confer on you the ability to reach forward to what is greater, and to bear fruit unto God. Attain therefore to the complete confidence that whatsoever ye shall ask in My name ye shall receive. Since, therefore, ye follow in the track of My words and ministry, and have the mind which My true disciples ought to be endued with, it follows that ye ought not by your own tarrying to throw obstacles in the way of him who of his will seeks the faith and is self-called to a life of piety; but that you should rather attach yourselves as guides to those who are still ignorant and astray, and bring to those who do not yet prefer to learn it the Gospel of salvation, and eagerly exhort them to attain unto the true knowledge of God, even though the mind of your hearers be hardened into disobedience. For thus they would be in your condition, that is, they will advance and will return by gradual growth in what is better to fruit-bearing in God, so as to have the fruit that ever remains and is preserved and that most acceptable object of prayer, the bestowal of whatsoever they wish, if only they ask in My name."
So much then on this head: for it is necessary again, compressing in a few words the drift of the text, to make it clear to our hearers. He persuades His disciples to have so much love towards others, and wishes them to exhibit as much zeal in their persistent endeavour in all directions to pursue and bring to holiness the souls of those who have not yet believed, as He Himself first showed towards us and them. For that He Himself chose His disciples is unquestioned, and I think it unnecessary to state how and in what way the call of each was made. Still, that the discourse of the Saviour is pregnant with the meaning I have just given to it what follows will equally persuade us. For he says:
