1. Baptism in Holy Spirit was the Father's promise to send Holy Spirit to empower Jesus's disciples to be His witness regarding the Father's character, plan, and purposes. By sending His only begotten son, He revealed Himself through Jesus's earthly ministry, death on the cross, rising from the dead, and ascension to His right hand.

2. The Plan of the Promise
Luke 24 (49) and behold, I am sending forth the promise of My Father upon you; but you are to stay in the city until you are clothed with power from on high.
Acts 1(4-5 & 8)But to wait for what the Father had promised, “Which,” He said, “you heard of from Me; 5 for John baptized with water, but you will be baptized with the Holy Spirit not many days from now; 8 but you will receive power when the Holy Spirit has come upon you; and you shall be My witnesses (mä'r-tüs-Martyr) both in Jerusalem, and in all Judea and Samaria, and even to the remotest part of the earth.” ( Jesus then ascended )

3. The Day of Pentecost Acts 2 (1-18)
 When the day of Pentecost had come, they were all together in one place. 2 And suddenly there came from heaven a noise like a violent rushing wind, and it filled the whole house where they were sitting. 3 And there appeared to them tongues as of fire distributing them selves, and they rested on each one of them. 4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit was giving them utterance.5 Now there were Jews living in Jerusalem, devout men from every nation under heaven. 6 And when this sound occurred, the crowd came together, and were bewildered because each one of them was hearing them speak in his own language!!!!

4. 7 They were amazed and astonished, saying, “Why, are not all these who are speaking Galileans? 8 And how is it that we each hear them in our own language to which we were born?9 Parthians and Medes and Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the districts of Libya around Cyrene, and visitors from Rome, both Jews and proselytes, 11 Cretans and Arabs—we hear them in our own tongues speaking of the mighty deeds of God.” 12 And they all continued in amazement and great perplexity, saying to one another, “What does this mean?” 13 But others were mocking and saying, “They are full of sweet wine.

5. 14 But Peter, taking his stand with the eleven, raised his voice and declared to them: “Men of Judea and all you who live in Jerusalem, let this be known to you and give heed to my words. 15 For these men are not drunk, as you suppose, for it is only the third hour of the day; 16 but this is what was spoken of through the prophet Joel:17 ‘AND IT SHALL BE IN THE LAST DAYS,’ God says, ‘THAT I WILL POUR FORTH OF MY SPIRIT ON ALL MANKIND; AND YOUR SONS AND YOUR DAUGHTERS SHALL PROPHESY, AND YOUR YOUNG MEN SHALL SEE VISIONS, AND YOUR OLD MEN SHALL DREAM DREAMS;18 EVEN ON MY BONDSLAVES, BOTH MEN AND WOMEN, I WILL IN THOSE DAYS POUR FORTH OF MY SPIRIT And they shall prophesy (The Message)

6. It’s not about tongues, it’s about the message!
1 Cor. 14(10-12 &18-19)  There are, perhaps, a great many kinds of languages in the world, and no kind is without meaning. 11 If then I do not know the meaning of the language, I will be to the one who speaks a barbarian, and the one who speaks will be a barbarian to me. 12 So also you, since you are zealous of spiritual gifts, seek to abound for the edification of the church.18 I thank God, I speak in tongues more than you all; 19 however, in the church I desire to speak five words with my mind so that I may instruct others also, rather than ten thousand words in a tongue.
The use of tongues started the church because it spoke to the world of Jews who were gathered for the “first fruits,’' Pentecost. Once the church was established tongues were for the believer’s edification. Paul stated unless there is the gift of interpretation It was more important to make sure the Message was clear.

7. The testimony of Jesus is the Spirit of Prophecy.
(The message)
Rev 19(10) Then I fell at his feet to worship him. But he *said to me, “Do not do that; I am a fellow servant of yours and your brethren who hold the testimony of Jesus; worship God. For the testimony of Jesus is the spirit of prophecy.”
1Cor 14(5) Now I wish that you all spoke in tongues, but even more that you would prophesy; and greater is one who prophesies than one who speaks in tongues, unless he interprets, so that the church may receive edifying.
"For God so loved the world…"

8. This baptism is about making you the temple.
Eze .36(27) “I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances.
1Cor 3(16) Do you not know that you are a temple of God and that the Spirit of God dwells in you?
Note: 2nd temple Judaism- the southern Kingdom of Judah and Benjamin (after returning from 70 years of captivity) were waiting for the promise of the Spirit of God to return to His Temple. Peter was declaring Joel's ancient prophecy had come true on this day of Pentecost, “I WILL POUR FORTH OF MY SPIRIT ON ALL MANKIND.”

9. I will pour out My Spirit in those days.
(Old Testament) Character and Promise of God
Joel 2(13) And rend your heart and not your garments.” Now return to the LORD your God, For He is gracious and compassionate, Slow to anger, abounding in loving kindness And relenting of evil.
Joel 2(27)  “Thus you will know that I am in the midst of Israel, And that I am the LORD your God, And there is no other; And My people will never be put to shame.
Joel 2(28-29)  “It will come about after this That I will pour out My Spirit on all mankind; And your sons and daughters will prophesy, Your old men will dream dreams, Your young men will see visions.29 “Even on the male and female servants
I will pour out My Spirit in those days.

10. (N.T.) Purpose of the Baptism in the Spirit
John 14 (16,18,26) “I will ask the Father, and He will give you another Helper, that He may be with you forever; “I will not leave you as orphans; I will come to you. “But the Helper, 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 said to you.
John 16(13-15)  But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. 14 He will glorify Me, for He will take of Mine and will disclose it to you. 15 All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose it to you.
Hebrews 1(3a) And He is the radiance of His glory and the exact representation of His nature, and upholds all things by the word of His power (The Father)

11. This Baptism is the Baptism of the Father's Love
Acts 2(33) “Therefore having been exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He has poured forth this which you both see and hear.
**** Romans 5(5) and hope does not disappoint, because the love of God has been poured out within our hearts through the Holy Spirit who was given to us.
“For God so loved the world”
“I will not leave you as orphans; I will come to you"

12. "Gods is Love" has always been Heaven's Message
1John 4(7-9) Beloved, let us love one another, for love is from God; and everyone who loves is born of God and knows God. The one who does not love does not know God, for God is love. By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.
Mark 12(28b-31), “What commandment is the foremost of all?” 29 Jesus answered, “The foremost is, ‘HEAR, O ISRAEL! THE LORD OUR GOD IS ONE LORD; 30 AND YOU SHALL LOVE THE LORD YOUR GOD WITH ALL YOUR HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND, AND WITH ALL YOUR STRENGTH.’ 31 The second is this, ‘YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.’ There is no other commandment greater than these.” (The goal the Ten commandments.)
