John 15:9

Our Lord showed above, that those who plotted against them should be burned, inasmuch as they abode not in Christ: now He shows that they themselves would be invincible, bringing forth much fruit; Herein is My Father glorified, that you bear much fruit: as if He said, If it appertains to My Father’s glory that you bring forth fruit, He will not despise His own glory. And he that brings forth fruit is Christ’s disciple: So shall you be My disciples.

The fruit of the Apostles are the Gentiles, who through their teaching were converted to the faith, and brought into subjection to the glory of God.

Made bright or glorified; the Greek word may be translated in either way. In Greek it signifies glory; not our own glory, we must remember, as if we had it of ourselves: it is of His grace that we have it; and therefore it is not our own but His glory. For from whom shall we derive our fruitfulness, but from His mercy preventing us. Wherefore He adds, As My Father has loved Me, even so love I you. This then is the source of our good works. Our good works proceed from faith which works by love: but we could not love unless we were loved first: As My Father has loved Me, even so love I you. This does not prove that our nature is equal to His, as His is to the Father’s, but the grace, whereby He is the Mediator between God and man, the man Christ Jesus. The Father loves us, but in Him.

If then I love you, be of good cheer; if it is the Father’s glory that you bring forth good fruit, bear no evil. Then to rouse them to exertion, He adds, Continue you in My love; and then shows how this is to be done: If you keep My commandments, you shall abide in My love.

Who doubts that love precedes the observance of the commandments? For who loves not, has not that whereby to keep the commandments. These words then do not declare whence love arises, but how it is shown, that no one might deceive himself into thinking that he loved our Lord, when he did not keep His commandments. Though the words, Continue you in My love, do not of themselves make it evident which love He means, ours to Him, or His to us, yet the preceding words do: I love you, He says: and then immediately after, Continue you in My love. Continue you in My love, then, is, continue in My grace; and, If you keep My commandments, you shall abide in My love, is, Your keeping of My commandments will be evidence to you that you abide in My love. It is not that we keep His commandments first, and that then He loves; but that He loves us, and then we keep His commandments. This is that grace, which is revealed to the humble, but hidden from the proud. But what means the next words, Even as I have kept My Father’s commandments, and abide in His love: i.e., the Father’s love, wherewith He loves the Son. Must this grace, wherewith the Father loves the Son, be understood to be like the grace wherewith the Son loves us? No; for whereas we are sons not by nature, but by grace, the Only Begotten is Son not by grace, but by nature. We must understand this then to refer to the manhood in the Son, even as the words themselves imply: As My Father has loved Me, even so love I you. The grace of a Mediator is expressed here; and Christ is Mediator between God and man, not as God, but as man. This then we may say, that since human nature does not pertain to the nature of God, but does by grace pertain to the Person of the Son, grace also pertains to that Person: such grace as has nothing superior, nothing equal to it. For no merits on man’s part preceded the assumption of that nature.

Even as 1 have kept My Father’s commandments. The Apostle explains what these commandments were: Christ became obedient to death, even the death of the cross (Phil 2:8).

Then because the Passion was now approaching to interrupt their joy, He adds, These things have I spoken to you, that my joy may remain in you: as if He said, And if sorrow fall upon you, I will take it away, so that you shall rejoice in the end.

And what is Christ’s joy in us, but that He deigns to rejoice on our account? And what is our joy, which He says shall be full, but to have fellowship with Him? He had perfect joy on our account, when He rejoiced in foreknowing, and predestinating us; but that joy was not in us, because then we did not exist: it began to be in us, when He called us. And this joy we rightly call our own, this joy wherewith we shall be blessed; which is begun in the faith of them who are born again, and shall be fulfilled in the reward of them who rise again.

2. This, therefore, was the [object of the] long-suffering of God, that man, passing through all things, and acquiring the knowledge of moral discipline, then attaining to the resurrection from the dead, and learning by experience what is the source of his deliverance, may always live in a state of gratitude to the Lord, having obtained from Him the gift of incorruptibility, that he might love Him the more; for “he to whom more is forgiven, loveth more:” and that he may know himself, how mortal and weak he is; while he also understands respecting God, that He is immortal and powerful to such a degree as to confer immortality upon what is mortal, and eternity upon what is temporal; and may understand also the other attributes of God displayed towards himself, by means of which being instructed he may think of God in accordance with the divine greatness. …

Hereto also I will add that view wherein the heretic, while he rejoices as if at the loss of some power of seeing special truth and light, acknowledges the total blindness of his error. For again and again, and frequently, he objects that it was said, “Have I been so long time with you, and do ye not know me, Philip? He who hath seen me, hath seen the Father also.” But let him learn what he does not understand. Philip is reproved, and rightly, and deservedly indeed, because he has said, “Lord, show us the Father, and it sufficeth us.” For when had he either heard from Christ, or learnt that Christ was the Father? although, on the other hand, he had frequently heard, and had often learned, rather that He was the Son, not that He was the Father. …

Ver. 9 . “As the Father hath loved Me, so have I loved you.” Here at length He speaketh in a more human manner, for this, as spoken to men, has its peculiar force. Since what a measure of love did He manifest, who chose to die, who counted worthy of such honor those who were His slaves, His haters, His open enemies, and led them up to the heavens! “If then I love you, be bold; if it be the glory of My Father that ye bear fruit, imagine nothing ill.” Then that He may not make them supine, observe how He braceth them again, “Continue ye in My love.” “For this ye have the power to do.” And how shall this be?

And yet the action was still but beginning, or rather was not yet beginning. How then said He, “I have finished”? Either He meaneth, that “I have done all My part”; or He speaketh of the future, as having already come to pass; or, which one may say most of all, that all was already effected, because the root of blessings had been laid, which fruits would certainly and necessarily follow, and from His being present at and assisting in those things which should take place after these. On this account He saith again in a condescending way, “Which Thou gavest Me.” For had He indeed waited to hear and learn, this would have fallen far short of His glory. For that He came to this of His own will, is clear from many passages. As when Paul saith, that “He so loved us, as to give Himself for us” ( Eph. v. 2 ); and, “He emptied Himself, and took upon Him the form of a servant” ( Philip. ii. …
