The Holy Spirit is the third person of the Trinity and is one with the Father and Son.
1 John 5:7 "For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one."
The Holy Spirit has part in Jesus' offering Himself and the resurrection of the dead.
Hebrews 9:14 "How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?"
Romans 8:11 "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."
There are two things on the earth right now that are Holy. These two things are the Holy Scriptures (KJB) and Holy Spirit. The Holy Spirit had part in the production of the Holy Scriptures and is needed to understand them.
2 Peter 1:21 "For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost."
2 Timothy 3:16 "All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:"
The main ministry of the Holy Spirit is to exalt the Lord Jesus Christ. This means the charismatics that exalt the Holy Spirit more than Jesus Christ are in the wrong.
There are several names of the Holy Spirit. Some of the names show relationship between the Father and the Son and some show his attributes and works. Here is a list...
- The good Spirit (Psalms 143:10, Nehemiah 9:20)
- The Spirit of God (Genesis 1:2, Matthew 3:16)
- The Spirit of grace (Hebrews 10:29)
- The Spirit of promise (Ephesians 1:13)
- The Spirit of glory (1 Peter 4:14)
- The Spirit of Christ (Romans 8:9)
- The Comforter (John 14:16)
- Eternal Spirit (Hebrews 9:14)
- Spirit of faith (2 Corinthians 4:13)
- Spirit of adoption (Romans 8:15)
- Spirit of wisdom and revelation (Ephesians 1:17)
- One Spirit (Ephesians 4:4)
The attributes and acts of the Holy Spirit prove his deity.
The Holy Spirit is omniscient, which means all knowing. This is shown in the below verses.
1 Corinthians 2:11 "For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. 12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God."
Omnipresent / Everywhere present
Psalms 139:7 "Whither shall I go from thy spirit? or whither shall I flee from thy presence?"
Omnipotent / All powerful
Zechariah 4:6 "Then he answered and spake unto me, saying, This is the word of the LORD unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the LORD of hosts."
The Holy Spirit convicts and reproves (John 16:7-8), guides (Romans 8:14), teaches (John 14:26) and testifies (John 15:26). He can be resisted (Acts 7:51), obeyed (Acts 10:19-21), grieved (Ephesians 4:30) and lied to (Acts 5:3).
The Holy Spirit also works in the process of salvation. The Holy Spirit convicts the lost person of his/her sin because the devil has blinded their mind according to 2 Corinthians 4:4. Some people believe you have to have a certain "feeling" to be saved, but that is not true. Holy Spirit conviction is not a feeling, rather the Holy Spirit showing the sinner his sin and need of salvation. You may or may not have a "feeling."
During salvation, the Holy Spirit regenerates us and baptizes us into the body of Christ.
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; 6 Which he shed on us abundantly through Jesus Christ our Saviour;"
1 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."
Also, when saved, we are sealed by the Holy Spirit until the Rapture.
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,"
The filling of the Holy Spirit is something we have to keep in check though. As believers, we have a spirit and a flesh and we are commanded to sow to the spirit instead of the flesh. We can do so by reading our Bible, praying, witnessing, living holy and etc.
Galatians 5:16 "This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh."
