Don't forget to mention the promise of Joel. The outpouring of the Spirit upon all flesh which occurred at Pentecost, for service. In other words, God wanted to pour out His Spirit on every believer, not just his chosen apostles and prophets, like Moses, Elijah etc, but everyone!. Young men, young men, servants, mothers, fathers, daughters, children. Jesus's ministry did not start until that happened, neither did the apostle's/early churches after Christ's ascension. I have never seen any Christian who does not believe in that subsequent experience of Pentecost (and yes, it may happen at conversion, but usually doesn't) speak in tongues, or exercise any of the spiritual gifts eg prophesy. Many, many Christians are deceived and content at just "being saved", and live a happy life involved in church programs or otherwise. Certainly they are saved. But don't expect to be receiving an encouraging word of prophecy from them or them to be able to heal you. Like one pastor I talked to about healing, he looked at me dumbfounded and had no clue. In that case, go to the world and see a medical doctor! Don't bother asking for prayer, it only make you skeptical and sad when they can't. And then they have this common excuse "it's not God's will". But they are the ones with the problem, not God. Because they aren't annointed with power !
If we think water baptism is enough, think again, scripture shows that this second experience is by prayer and or laying on of hands by an apostle (or other anointed church leader):
Act 8:15 Who, when they were come down, prayed for them, that they might receive the Holy Ghost:
Act 8:16 For as yet He had not fallen on any of them, they were baptized only in the name of the Lord Jesus.
Act 8:17 Then they laid their hands on them, and they received the Holy Spirit.
Act 8:18 And when Simon saw that the Holy Spirit was given through laying on of the apostles' hands, he offered them money,
