THE ANNUNCIATION
Then the angel said to her, "Do not be afraid, Mary, for you have found favor with God.
Behold, you will conceive in your womb and bear a son, and you shall name him Jesus.
He will be great and will be called Son of the Most High,
and the Lord God will give him the throne of David his father,
and he will rule over the house of Jacob forever, and of his kingdom there will be no end."
But Mary said to the angel, "How can this be, since I have no relations with a man?"
And the angel said to her in reply, "The Holy Spirit will come upon you,
and the power of the Most High will overshadow you.
Therefore the child to be born will be called holy, the Son of God.
Gospel of Luke 1:30-35

"For the Holy Spirit will teach you at that moment what you should say."
Gospel of Luke 12:12

And John bore witness, "I saw the Spirit descend as a dove from heaven, and it remained on him.
I myself did not know him; but he who sent me to baptize with water said to me,
'He on whom you see the Spirit descend and remain, this is he who baptizes with the Holy Spirit.'
And I have seen and have borne witness that this is the Son of God."
Gospel of John 1:32-34

Jesus answered, "Truly, truly, I say unto you,
unless you be born again of the water and the Spirit,
you cannot enter into the kingdom of God"
Gospel of John 3:5

Jesus answered her, "If you knew the gift of God, and who it is that is saying to you, 'Give me a drink,' you would have asked him, and he would have given you living water." The woman said to him, "Sir, you have nothing to draw with, and the well is deep; where do you get that living water? Are you greater than our father Jacob, who gave us the well, and drank from it himself, and his sons, and his cattle?" Jesus said to her, "Every one who drinks of this water will thirst again, but whoever drinks of the water that I shall give him will never thirst; the water that I shall give him will become in him a spring of water welling up to eternal life."
Gospel of John 4:10-14

On the last day of the feast, the great day, Jesus stood up and proclaimed, "If any one thirst, let him come to me and drink. He who believes in me, as the scripture has said, 'Out of his heart shall flow rivers of living water [Ezekiel 36:25].'" Now this he said about the Spirit, which those who believed in him were to receive; for as yet the Spirit had not been given, because Jesus was not yet glorified.
Gospel of John 7:37-39

THE COUNSELOR
"And I will pray the Father, and he will give you another Counselor, to be with you for ever,
even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him;
you know him, for he dwells with you, and will be in you."
Gospel of John 14:16-17

"But the Counselor, the Holy Spirit, whom the Father will send in my name,
he will teach you all things, and bring to your remembrance all that I have said to you.
Peace I leave with you; my peace I give to you;
not as the world gives do I give to you."
Gospel of John 14:26-27

"Nevertheless I tell you the truth: it is to your advantage that I go away, for if I do not go away,
the Counselor will not come to you; but if I go, I will send him to you.
And when he comes, he will convince the world concerning sin and righteousness and judgment.
Gospel of John 16:7-8

"When the Spirit of truth comes, he will guide you into all the truth; for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come. He will glorify me, for he will take what is mine and declare it to you. All that the Father has is mine; therefore I said that he will take what is mine and declare it to you."
Gospel of John 16:13-15

Jesus said to them again, "Peace be with you. As the Father has sent me, even so I send you."
And when he had said this, he breathed on them, and said to them, "Receive the Holy Spirit.
If you forgive the sins of any, they are forgiven;
if you retain the sins of any, they are retained."
Gospel of John 20:21-23

THE PENTECOST
"When the time for Pentecost was fulfilled, they were all in one place together.
And suddenly there came from the sky a noise like a strong driving wind,
and it filled the entire house in which they were.
Then there appeared to them tongues as of fire, which parted and came to rest on each one of them.
And they were all filled with the holy Spirit and began to speak in different tongues,
as the Spirit enabled them to proclaim."
Acts of the Apostles 2:1-4

If the Spirit of the one who raised Jesus from the dead dwells in you,
the one who raised Christ from the dead will give life to your mortal bodies also,
through his Spirit that dwells in you.
The Epistle of St. Paul to the Romans 8:11

Do you not know that your body is a temple of the Holy Spirit within you,
whom you have from God, and that you are not your own?
The First Letter of St. Paul to the Corinthians 6:19

For the flesh has desires against the Spirit, and the Spirit against the flesh;
these are opposed to each other,
so that you may not do what you want.
But if you are guided by the Spirit, you are not under the law.
Now the works of the flesh are obvious: immorality, impurity, licentiousness, idolatry, sorcery, hatreds, rivalry, jealousy, outbursts of fury, acts of selfishness, dissensions, factions, occasions of envy, drinking bouts, orgies, and the like.
I warn you, as I warned you before,
that those who do such things will not inherit the kingdom of God.
In contrast, the fruit of the Spirit is love, joy, peace, patience, kindness, generosity, faithfulness, gentleness, self-control. Against such there is no law.
Now those who belong to Christ Jesus have crucified their flesh with its passions and desires.
If we live in the Spirit, let us also follow the Spirit.
St. Paul to the Galatians 5:17-25

Knowing this first, that no prophecy of scripture is of private interpretation.
For no prophecy ever came by the will of man:
but men spoke from God, being moved by the Holy Spirit.
II Peter 1:20-21
