Acts 2:37-39 37 Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, "Men and brethren, what shall we do?" 38 Then Peter said to them, "Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit. 39 "For the promise is to you and to your children, and to all who are afar off, as many as the Lord our God will call." (NKJ)
Acts 5:32 "And we are His witnesses to these things, and so also is the Holy Spirit whom God has given to those who obey Him." (NKJ
Acts 15:8-9 8 "So God, who knows the heart, acknowledged them by giving them the Holy Spirit, just as He did to us, 9 "and made no distinction between us and them, purifying their hearts by faith. (NKJ)
Acts 10:44-48 44 While Peter was still speaking these words, the Holy Spirit fell upon all those who heard the word. 45 And those of the circumcision who believed were astonished, as many as came with Peter, because the gift of the Holy Spirit had been poured out on the Gentiles also. 46 For they heard them speak with tongues and magnify God. Then Peter answered, 47 "Can anyone forbid water, that these should not be baptized who have received the Holy Spirit just as we have?" 48 And he commanded them to be baptized in the name of the Lord. Then they asked him to stay a few days. (NKJ)
9. Baptism of Holy Spirit is given when we believe on/in Jesus, (provided that the convert is instructed concerning this truth and exercise’s faith to receive it, (Acts 19:1-6, 11:15-17, Gal 4:6, Jn 7:37-39)
So how doe's someone KNOW when he has been baptism in the H.S.? He will have at least one (maybe more) of the 9 manifestation's of the H.S. operating in and through him. Mk 16:16-18 16 "He who believes and is baptized will be saved; but he who does not believe will be condemned. 17 "And these signs will follow those who believe: In My name they will cast out demons; they will speak with new tongues; 18 "they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover." (NKJ) Cor 12:7-13 7 But the manifestation of the Spirit is given to each one for the profit of all: 8 for to one is given the word of wisdom through the Spirit, to another the word of knowledge through the same Spirit, 9 to another faith by the same Spirit, to another gifts of healings by the same Spirit, 10 to another the working of miracles, to another prophecy, to another discerning of spirits, to another different kinds of tongues, to another the interpretation of tongues. 11 But one and the same Spirit works all these things, distributing to each one individually as He wills. 12 For as the body is one and has many members, but all the members of that one body, being many, are one body, so also is Christ. 13 For by one Spirit we were all baptized into one body-- whether Jews or Greeks, whether slaves or free-- and have all been made to drink into one Spirit. (NKJ)
Well, by now it should be obvious that when Peter said in Acts 2:38 "...Repent, and let everyone of you be baptized in the name of Jesus Christ for the remission of sin's: and you SHALL (not 'maybe', or might!), receive the gift of the H.S." That he was giving us 3 essential's to salvation (i.e. from Pentecost on). There can be no doubt that the true Church of Jesus Christ operates in the manifestations of the Spirit today, just as the first century churche's did! For the Scripture say's:
Mk 16:17-18 17 "And these signs will follow those who believe: In My name they will cast out demons; they will speak with new tongues; 18 "they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover." (NKJ) (note: these sign's follow those who BELIEVE; not just to first century believer's; nor just until the so called "cannon" was complete; but for those who believe throughout the centuries!)
John 14:12 "Most assuredly, I say to you, he who believes in Me, the works that I do he will do also; and greater works than these he will do, because I go to My Father. (NKJ) (once again; this promise is made to those who BELIEVE)!
Acts 2:37-39 37 Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, "Men and brethren, what shall we do?" 38 Then Peter said to them, "Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit. 39 "For the promise is to you and to your children, and to all who are afar off, as many as the Lord our God will call." (NKJ) (notice that the promise of the baptism of the H.S. is promised to "as many as the Lord our God will call." And no one come's to God unless he call's them. Hence this promise is for every believer today)!
I Cor 2:4-5 4 And my speech and my preaching were not with persuasive words of human wisdom, but in demonstration of the Spirit and of power, 5 that your faith should not be in the wisdom of men but in the power of God. (NKJ)
I Cor 4:19-20 19 But I will come to you shortly, if the Lord wills, and I will know, not the word of those who are puffed up, but the power. 20 For the kingdom of God is not in word but in power. (NKJ) (notice that the Kingdom of God is not in word only; but in power!
The word Power = Strong's # 1411 dunamis (doo'-nam-is); from 1410; force (literally or figuratively); specially, miraculous power (usually by implication, a miracle itself): KJV-- ability, abundance, meaning, might (-ily, -y, -y deed), (worker of) miracle (-s), power, strength, violence, mighty (wonderful) work. (DIC)
This is the same word used by Jesus in Acts 1:8 "But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth." (NKJ)
In Acts 2:1-38 we see the beginning of what type of power was meant by Jesus. And it is this type of power that those who are in the Kingdom of God have. So it stand's to reason that if you and the church you are attending do not have this power operating in you/it. You/it have not yet entered the Kingdom of God! So then: all of the churche's that don't have God's power being manifested in there service's; are filled with non-Christians. For God's Kingdom is not in word only; but in power! And those who are in God's Kingdom, have God's power! Therefore if you do not have God's power; be zealous and repent; asking God to baptize you in the Holy Spirit. And Keep on asking until you get it!
