For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. - John 3:16

Baptism of the Holy Spirit

The baptism with, by, in or of the Holy Ghost (Holy Spirit) is part of New Testament salvation (Romans 8:11;But if the Spirit of him that raised up Jesus from the dead dwell in you, he raised up that Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you. John 3:5;Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. I Corinthians 12:13;For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit. Ephesians 1:13-14;In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory. Titus 3:5).Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;

But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness. But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you. Therefore, brethren, we are debtors, not to the flesh, to live after the flesh. For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live. (Romans 8:9-13)
The phrase describes how the believer is immersed in and filled with God’s Spirit. In Acts the terms “baptized, filled, received, fell on, came upon, and poured out the gift on” all describes the experience (Acts 1:4-5;And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence. 2:4;And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. 10:44-47;While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost. For they heard them speak with tongues, and magnify God. Then answered Peter, Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? 11:15-17;And as I began to speak, the Holy Ghost fell on them, as on us at the beginning. Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost. Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God?
He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost. And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism. Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus. When they heard this, they were baptized in the name of the Lord Jesus. And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied. (19:2-6)

Promise For Everyone

It is promised by to all who believe on Jesus and obey His Word - (Acts 5:32;And we are his witnesses of these things; and so is also the Holy Ghost, whom God hath given to them that obey him. 11:16;Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost. 19:2;He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost. Galatians 3:14;That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith. Ephesians 1:13).In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water. (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.) (John 7:38-39)

Receiving the Holy Spirit Historical Accounts

The Bible records five historical accounts of receiving the Holy Spirit in the New Testament church: the Jews, the Samaritans, the Gentiles, the apostle Paul, and the disciples of John at Ephesus. This record establishes that the baptism of the Spirit is indeed for everyone (Luke 11:13;If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him? Acts 2:39)For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call. and is accompanied by the initial sign of tongues (Mark 16:17).And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; Speaking in tongues means speaking supernaturally, as the Spirit gives utterance, in a language the speaker has never learned.

And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans? And how hear we every man in our own tongue, wherein we were born? (Acts 2:1-8).

Initial Evidence is Speaking in Tongues

Three of the accounts explicitly describe speaking in tongues as the initial evidence of receiving the Spirit. On the Day of Pentecost, a sound of wind signified the coming of the Spirit and tongue-like flames signaled the availability to each person, but speaking in tongues “as the Spirit gave them utterance” was the initial sign of each individual filling (Acts 2:1-4).And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. Tongues convinced skeptical, astonished Jews that the Gentiles had just received the Holy Ghost; tongues alone sufficiently identified this as the Pentecostal experience (Acts 11:15-17).And as I began to speak, the Holy Ghost fell on them, as on us at the beginning. Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost. Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God?

While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost. For they heard them speak with tongues, and magnify God. Then answered Peter, Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? (10:44-47)
The Ephesian disciples also spoke in tongues as the first sign of receiving the Spirit (Acts 19:6).And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.

New Testament Experience

The baptism of the Holy Spirit is the normal, basic New Testament experience with God, the birth of the Spirit. The Spirit is the rest, guide to all truth, adopter, intercessor, seal, earnest of inheritance, and sanctifier (Isaiah 28:11-12;For with stammering lips and another tongue will he speak to this people. To whom he said, This is the rest wherewith ye may cause the weary to rest; and this is the refreshing: yet they would not hear. John 16:13;Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. Romans 8:15,r ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father. 26;Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered. I Peter 1:2).Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.

In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory. (Ephesians 1:13-14)
Someone can receive the Spirit by repenting, having faith in God, and asking God for His gift. When a person receives the Holy Spirit, he receives power to overcome sin and live a holy life (Acts 1:8;But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. Romans 8:4,That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit. 13).For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live. If he lets the Spirit continually fill (control and guide) him, he will bear the fruit of the Spirit and become Christ-like.
But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law. (Galatians 5:22-23).
