He is not just everywhere, but also above all, not just in every age and time, but before them all. And, according to the promise, the Holy Spirit will not just be with us until the end of the age, but rather will stay with those who are worthy in the age to come, making them immortal and filling their bodies as well with eternal glory, as the Lord indicated by telling His Disciples, "I will pray to the Father, and He shall give you another Comforter, that He may abide with you forever" (St. John 14:16).

A short while ago, with the strong eyes of faith, we beheld Christ ascending, no less clearly than those accounted worthy to be eye-witnesses. Nor are we less favored than they, "Blessed are they that have not seen, and yet have believed", says the Lord (St. John 20:29), referring to those who have found assurance through hearing, and see by faith. Recently we saw Christ, lifted up from the ground bodily (Acts 1:9). Now, through the Holy Spirit sent by Him to His Disciples, we see how far Christ ascended and to what dignity He carried up the nature He assumed from us.

As soon as the Holy Apostles were filled with the Holy Spirit they were full of great joy. It was a new experience for them. While previously they had simply been good men, now they became members of the Risen Body of Christ. They were not confined to worshipping Christ, but they were inseparably united with Him. All who saw them were perplexed, and some mockingly said "they are full of new wine", meaning they were drunk with new wine (Acts 2:13).

The feast of Pentecost is a feast of the Holy Spirit, because we learn from the descent of the Holy Spirit that God is Three-fold. Previously too, both obscurely in the Old Testament and in Christ's teaching, people were learning the Trinitarian character of God, but at Pentecost they acquired practical experience of His threefold hypostasis. Thus Pentecost is a feast of orthodox theology.

Before Christ ascended into Heaven He gave a command to His Disciples to return to Jerusalem after His Ascension and remain there until they were invested with power from Heaven. Thus He gave them the promise that they would receive the Holy Spirit, about which He had spoken during His life.

So, while we have been called for this great purpose; to unite with God; to become gods by Grace; and to enjoy this great blessing for which our Maker and Creator made us, we often live as if this great and noble aim does not exist for us. Because of this, our life is filled with failure. Our Holy God molded us for Theosis (Deification), so if we are not deified, our whole life is a failure.
