Acts 2:1–4 (ESV) 2 When the day of Pentecost arrived, they were all together in one place. 2 And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. 3 And divided tongues as of fire appeared to them and rested on each one of them. 4 And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.

Acts 2:38–39 (ESV) 38 And Peter said to them, “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. 39 For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself.”

9 And I tell you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. 10 For everyone who asks receives, and the one who seeks finds, and to the one who knocks it will be opened. 11 What father among you, if his son asks for a fish, will instead of a fish give him a serpent; 12 or if he asks for an egg, will give him a scorpion? 13 If you then, who are evil, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask him!” Luke 11:9–13 (ESV)

24 Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours. Mark 11:24 (ESV)

4 And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance. Acts 2:4 (ESV)

38 Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.’ ” John 7:38 (ESV)
