1. To permanently indwell every believer.
When the day of Pentecost came, they were all together in one place. Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them. Acts 2:1-4
And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit, who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory. Ephesians 1:13-14
“If you love me, keep my commands. And I will ask the Father, and he will give you another advocate to help you and be with you forever—the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you.
2. To equip and empower every believer to take part in the spread of the gospel.
“Fellow Israelites, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles, wonders and signs, which God did among you through him, as you yourselves know. This man was handed over to you by God’s deliberate plan and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross. But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him. David said about him:
“‘I saw the Lord always before me.
Because he is at my right hand,
I will not be shaken.
Therefore my heart is glad and my tongue rejoices;
my body also will rest in hope, because you will not abandon me to the realm of the dead,
you will not let your holy one see decay.
You have made known to me the paths of life;
you will fill me with joy in your presence.’
“Fellow Israelites, I can tell you confidently that the patriarch David died and was buried, and his tomb is here to this day. But he was a prophet and knew that God had promised him on oath that he would place one of his descendants on his throne. Seeing what was to come, he spoke of the resurrection of the Messiah, that he was not abandoned to the realm of the dead, nor did his body see decay. God has raised this Jesus to life, and we are all witnesses of it. Exalted to the right hand of God, he has received from the Father the promised Holy Spirit and has poured out what you now see and hear. For David did not ascend to heaven, and yet he said,
“‘The Lord said to my Lord:
“Sit at my right hand
until I make your enemies
a footstool for your feet.”’
“Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Messiah.” Acts 2:22-36
Each of you should use whatever gift you have received to serve others, as faithful stewards of God’s grace in its various forms. 1 Peter 4:10
So Christ himself gave the apostles, the prophets, the evangelists, the pastors and teachers, to equip his people for works of service, so that the body of Christ may be built up Ephesians 4:11-12
3. To create and build the church up into an active new community of faith.
When the people heard this, they were cut to the heart and said to Peter and the other apostles, “Brothers, what shall we do?”
Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. The promise is for you and your children and for all who are far off—for all whom the Lord our God will call.”
With many other words he warned them; and he pleaded with them, “Save yourselves from this corrupt generation.” Those who accepted his message were baptized, and about three thousand were added to their number that day.
They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer. Acts 2:37-42
