In this is my Father glorified, that you bear much fruit; so shall you be my disciples.

Cyril of Alexandria
AD 444
He says that God His Father has been glorified, being justly admired for His incomparable goodness and crowning as it were His exceeding kindness with actual proof. For He so loved the world according to the Scripture, that He gave His Only-begotten Son, that whosoever believeth on Him should not perish, but have eternal life. The life of all, that of course which is fulfilled by Christ, is then the fruit of the kindness of God the Father. For this reason I suppose He Himself, conversing with God the Father, said: I glorified Thee on the earth, having accomplished the work which Thou hast given Me to fulfil it. For the Only-begotten, being entrusted as it were with the salvation of us all, has well accomplished it by the Father, and He a Being not comprehended under the condition of necessary obedience, but Himself the absolute wisdom and power of His Father, apart from Whom nothing whatever can exist. For all things are by Him, according to the Holy Evangelist, and we in a special manner. And for this reason the blessed David declares that the ordering of all that concerns us, and the directing aright of the life of all is entrusted by the Father to the Son, as His power and wisdom, when he says: O God, order the working of Thy power: O God, confirm that which Thou hast prepared; and once more: O God, give Thy judgment to the King. For it was the work of Him Who alone reigns with God the Father to restore the earth that was entirely corrupted, and to be able to mould it anew into its former state. Therefore My Father was glorified by giving His Own Son as a ransom for the life of the world, being content to see among us Him Who is above every creature, not that He might bring any addition of perfection to His Own Nature. For He is all perfect and self-sufficing, having power over all things, but in order that you may bring forth more fruit and become My disciples. For if He had not become man, we should not, being deemed worthy of sharing His nature, and being united to Him like branches, and gaining for Him the power of bearing fruit by sharing in His Spirit, have produced the fruit of a state of life pleasing to God, which He even calls much, putting in the background that which sprang from service of the Law, and showing that it is of less importance. For the Law hath made nothing perfect, according to the saying of Paul. For this reason He said to His holy disciples, nay to all of us who have been united to Him by faith and perfect love: Verily, verily I say unto you, Except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no wise enter into the kingdom of heaven. And again: Every scribe who hath been made a disciple to the kingdom of heaven, is like unto a rich man which bringeth forth out of his treasure things new and old; casting, as it were, from the treasury of their hearts the Mosaic injunctions, and the memory of the ancient writings. He therefore, who is a willing hearer, and ready to learn, and is full of the torchlight of the Gospel, has his wealth increased and multiplied; I mean, of course, spiritual wealth. For he brings forth things new and old, transforming the shadow of the Law and the power of servitude to the Law into the pattern of citizenship according to the Gospel. For what the Law figured by types, this Christ did openly in truth. Wherefore also He said: I came not to destroy the Law, but to fulfil; and again: Verily, verily, I say unto you, one jot or one tittle shall in no wise pass away from the Law, till all things be accomplished. The power then of the service of the Gospel is the much fruit, spiritual, and in truth; seeing that the Only-begotten became Man for the glory of God the Father. And on this account it has followed that those who are on the earth are His disciples. For He spoke to those of old time and formerly through the prophets as God; but has told us and said concerning us: And they shall all be taught of God. For to us who believe in Him, not merely has no other person intervened and conveyed the message from Him, or become a mediator of His Will towards us, as Moses doubtless was to the Israelites in Mount Sinai: or again, the prophets after Moses to those among them; but Christ Himself has taught us. And for this reason we are all taught of God. We should not then have at all become His disciples, we should not have brought forth the fruits of love towards God, and this in abundance, unless the Father had been glorified by His goodness, taking such pleasure in us, that the Word proceeding from His Essence should become Man. For we shall think thus when we hear the Holy Scripture declaring that He gave His own Son. For He also approved of His choosing to suffer this for us; and, on this account, is said to have given Him: and with justice.
