God is Holy Spirit. The Holy Spirit is Deity. (Acts 5:3,4). He has existed with God from the beginning as His breath, even before time as do God the Father and His Word. (Gen 1:2).

When God breaths, the Holy Spirit proceeds from the Father as His spirit. Likewise, when God spoke, Christ proceeded from the Father as His word (expression?). (Jn 8:42; Jn 15:26).

Jesus, the Son and express image of God’s person, breathed on His disciples (after His resurrection and glorification) and said unto them, “You receive the Holy Ghost”. (Jn 20:22). The Holy Spirit is His breath too, not the natural breath that kept His body alive. He is the Breath that raises the dead spirit in us.
When believers receive our glorious bodies, the Holy Spirit will be the breath of our transformed, immortal bodies too – certainly not the kind that we breath for the survival of our natural bodies; not the air made of Nitrogen and Oxygen. O2 is for the Red Blood Corpuscles. Our glorious bodies will not have this blood. Flesh and blood do not inherit the kingdom of God! 1 Cor 15:50.

The Holy Spirit is not the third person of the Triune God; not 1/3. No such order is mentioned in the Scriptures; (Neither is Jesus Christ the second person of the Trinity). He is integral of the One and is united (uno is one) with the others in the Trinity. For there are three that bear record in heaven: the Father, the Word, and the Holy Ghost: and these three are One (1John 5:7) That is why when the Holy Spirit comes to dwell in man, the Son of God the Lord Jesus Christ, and His Father also come in simultaneously, not one after another. (Jn 14:23). Did not Jesus mention, “The Father has not let me alone”? (Jn 8:29), and again, “I am not alone because the Father is in me”. (Jn 16:32).

He brings about the communion between man and God, and man and man (among believers). (2 Cor 13:14). It is for this same reason that Jesus instructed His disciples to mention (the name of) the Father, Son and the Holy Spirit at the believers’ baptism. The believer must be aware of the existence of the trinity; only then would we know that the presence of the Holy Spirit (and the fullness) is essential for living a life pleasing to God. (Matt 28:19; Acts 19:1-7). Twelve Ephesian disciples did not know this. (Acts 19:1-7). They could not even be counted as Christian believers.

(1) The Spirit of the LORD shall rest upon Him (Jesus) , (2) the Spirit of wisdom and (3) understanding, (4) the spirit of counsel and (5) might, (6) the spirit of knowledge and of (7) the fear of the LORD. (Isa 11:2). - the seven Spirits (Rev 1:4; 3:1; 4:5; 5:6 indicating perfection) merging into one Holy Spirit. This happened right when Jesus was immaculately conceived in the womb of Mary (Matt 1:18; Luke 1:35). This happened in private.

“I will put my Spirit upon Him, and He shall shew judgment to the Gentiles” (Matt 12:18). John saw the Holy Spirit descending from heaven and resting on the Lord Jesus at the river Jordan like a dove; people heard the voice; (Jn 1:32, 33). While the Holy Spirit already remained in Him fully during His entire sojourn on earth as Man, all the thirty-three and a half years (not just the three and a half), this was the public manifestation of the baptism of the Holy Spirit on Jesus, without which the Jewish public would not have known this at all. He was justified in the Spirit, the Father testifying of Him, “This is my beloved Son (Matt 17:5) in whom I am well pleased”, (Matt 3:17) not once but on two different occasions; the first time was when Jesus had not even started His ministry – not one word spoken, not one healing done, not one miracle performed, not one evil spirit cast out.

The Holy Spirit empowered the Man Christ Jesus to do the will of His Father and fulfil the purpose of God while on earth. (Heb 9:14). He went about doing good and healing all that were oppressed of the devil (Acts 10:38). He read from Isa 61:1-3, even at the beginning of His ministry: “The Spirit of the Lord is upon me, because He hath anointed me to preach the gospel to the poor; He hath sent me to heal the broken-hearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, to preach the acceptable year of the Lord”. (Luke 4:18, 19). The Lord is (that) Spirit: and where the Spirit of the Lord is, there is liberty. (2 Cor 2:17).

The last activity that the Lord Jesus Christ did on this earth through the Holy Spirit was command His disciples to wait for the arrival of the Holy Ghost with power “after that the Holy Ghost is come upon you: and you shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth” (Acts 1:4, 8).

The Holy Spirit is essential for man to know the things of God and the things that are freely given to us of God. (1 Cor 2:11, 12). The natural man can’t receive these things of God as he does not even know these things exist. A believer can’t earn these.

God (the Holy Spirit as per the Tamil Bible) inspired chosen men to write scriptures (2 Tim 3:16, 17; Heb 3:7; 2 Pet 1:21); He is the Author of every word, jot, and tittle. (Gal 3:16). Even the singular of a noun matters a lot (and a plural would not fit the purpose of God!) However, the human writers used their unique style to convey the message to the readers; some were songs, some were poetry, some were prose, and some were commentaries. God, in some cases, used worldly education of man for His purpose! Moses, Luke and Paul are examples.

After Jesus fulfilled the Old Testament law to its entirety (Matt 5:17), it seemed good to the Holy Spirit to not lay upon the gentiles of NT times a greater burden than the necessary things: “abstain from (1) meats offered to idols, and (2) blood, and (3) things strangled, and (4) fornication: from which if you keep yourselves, you shall do well”. (Acts 15:29). “My yoke is easy, and My burden is light” said Jesus (Matt 11:30). Truly light, indeed!

A (holy) spiritual person is one whose spirit has been quickened by God and who has the Holy Spirit within. Such a person can judge / discern all things (1 Cor 2:15; 1 Jn 3:20; 2:20, 27); however, he / she cannot be discerned by any ordinary man (1 Cor 2:14). The darkness cannot comprehend it! (Jn 1:5). He is not a carnal person given to the works of the flesh. (Gal 5:19-21).

During Old Testament times (before the first advent of Jesus on earth in the likeness of sinful flesh), the Holy Spirit descended momentarily on individuals to accomplish a special purpose, most of the time to reveal God’s will for the present or the future. (Some did exploits). God, spoke in time past by the prophets (Heb 1:1). Enoch was the first; Job was another; Moses was the primary prophet; David prophesied by the Spirit (Ps 110:1). Another Psalmist instructed the people by the Spirit: (Ps 95:7, 8).

The Holy Ghost spoke by Esaias the prophet (Isa 6:9, 10). Jeremiah, Ezekiel and Daniel followed; Hosea to Malachi, prophets kept appearing at sundry times; Zacharia, the father of John the Baptist, was filled with the Holy Ghost and prophesied (Luke 1:67) about the Saviour. John the Baptist was the last of such Old Testament prophets. Simeon had the Holy Spirit upon Him (Luke 2:25, 26) when he visited the temple on the day Jesus was brought in for the first time. However, it was not necessary that the person was a believer; even ungodly seers like Balaam were taken hold by God’s Spirit to prophesy. In fact, a significant prophecy about Jesus was spoken by the Spirit through Balaam: “There shall come a Star out of Jacob, and a Sceptre shall rise out of Israel…Out of Jacob shall come He that shall have dominion, and shall destroy …”. Caiaphas was another.

Many others also (even King Saul) prophesied when the Spirit came on them. However, only their body and its members and senses were taken over by the Spirit to see, hear and speak or do something supernatural. The Spirit could not dwell in them because they were not ‘born again’ and Christ was not in them as their life; their sins could only be covered. Dwelling became possible only in New Testament times when the ‘anointed One’ comes into the life of believers at our salvation. And, the Holy Spirit can comfortably remain on Jesus and in us for ever.
