The knowledge of the Lord's unity with God the Father now removes from them the thought that the Lord, apart from the flesh, will pray to the Father for them. In the flesh, the God-man, as man, prays to God the Father for believers (cf. Jn 17:20 and the whole chapter). For He was man in soul and body, and as such "fulfilled all human righteousness" (Mt 3:15). Yet as God He will receive prayer.
Being one with the Father, He Himself fulfills their prayer spoken in His name. He thereby points to the distinct honoring of the Hypostases, and also unites Them in the fulfillment of human prayer. This is the prayer which, as we said above, is inspired in us by the Holy Spirit, "interceding in us with groanings too deep for words" (Rom 8:26).
God, manifested to humanity within the limits of space and time, the second Hypostasis of the Holy Trinity, who reveals the invisible and incomprehensible God, requires nothing from man except faith and love.
A few simple men, yet chosen by God, loved the incarnate God with their souls and gave Him their souls. This love and faith of mortal creatures toward the immortal God incarnate is rewarded with joyful immortality. The Holy Spirit shows no partiality, says Cyril of Jerusalem, for He seeks not rank, but reverence of soul.
The Lord explains to the disciples: "For the Father Himself loves you, because you have loved Me and have believed that I came forth from God." Therefore everyone who believes and loves the Lord Jesus is loved by God, for the Lord Jesus Himself is God.
"I came forth from the Father," says the Lord, "and have come into the world. Again, I leave the world and go to the Father."
The world is one of the glorious manifestations of the will of God, and the laws God established for it are firm and unchangeable. But the material world, with its organic and animal life, is not complete without man. In man, the soul, as a share of divinity granted to him, is the bond of man and of the whole world with God.
This human soul, with its free will, could depart and did depart from the moral laws. It had to be removed from God, the source of all righteousness, as unworthy of God, unless God Himself came to redeem this soul.
He came to make it worthy to be received into communion with the Godhead, "that God may be all in all" (1 Cor 12:6; 15:28; cf. Eph 1:23), by the mercy and sacrifice of the Lord Jesus.
The Lord Jesus, the pre-eternal Word of God, says: "I came forth from the Father and have come into the world." The world is not part of the Godhead, but only a part of infinity and eternity held in the hands of God.
Therefore God, entering the world, takes upon Himself the limitation of time and space. And when He says, "Again, I leave the world and go to the Father," He indicates that He loosens these bonds when, within them, He has fulfilled the dread Sacrifice before the righteousness of God.
Yet the very coming of God into the world illumined the world with radiance. As a human being is illumined by the Holy Spirit, "as when the bright shining of a lamp gives him light" (Lk 11:36), so also the world, by being visited by God in the flesh, received the Holy Spirit. From then and forever, He illumines all human actions.
Let us not be troubled when we see that in some places on earth the light grows dim in souls that surrender themselves to the corruption of unbelief. It shines more brightly in other places, where there is no self-deification of man, that supremely satanic sin.
Let us remember what the Lord said of His Church: "The gates of Hades shall not prevail against it" (Mt 16:18).
We shall end this section on the unity of God the Father and the Lord Jesus, who came into the world and ascends from the world to the Father. With the words of Athanasius the Great: "The distinctive mark of faith in Christ is that the Son of God, the true Word of God (Jn 1:1), the true wisdom and power of the Father (1 Cor 1:24), at the end of the ages became man for our salvation."
"He is true man and, together with this, God, now at the right hand of the Father, being in the Father, and the Father in Him always."
