God is a Spirit. Only God is Holy. God IS the Holy Spirit.

God is a Spirit. 

• God is a Spirit:... John 4:24.

(The Jews call Him Elohim, the one God of all.)

Only God is holy, Holy, HOLY (Isaiah 6:3 and Revelation 4:8), and the entire concept of holiness is only associated with God, because true holiness is only of and from God.

Knowing only God is Holy by nature and God is a Spirit (John 4:24), we know God is not only a holy Spirit, He is THE Holy Spirit. 

Never forget, ALL of God IS the one and only Holy Spirit, because no other Spirit is Holy. Thus, each and every aspect of God is also the Holy Spirit. 

• There is one body, and one Spirit, even as ye are called in one hope of your calling;... Ephesians 4:4.

God is almighty and supreme, and everything was created by God as THE Father of everything; otherwise, He is not God.

• One Lord, one faith, one baptism, One God and Father of all, who is above all, and through all,... Ephesians 4:5-6.
• Wherefore let them that suffer according to the will of God commit the keeping of their souls to him in well doing, as unto a faithful Creator. 1 Peter 4:19.

As a loving Father, God is THE Father to all who want to be His children. His children call Him Father. 

• And call no man your father upon the earth: for one is your Father, which is in heaven. Matthew 23:9.

As explained in the next sections, according to the Bible not all people are His children, despite what you may think or have been taught previously. That said, all who believe in Him are given the power to become the children of God. 

• But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: John 1:12.

Thus, God is also love.

• …God is love. 1 John 4:8 and 16.

(Please note that the God-kind of love is clearly different from mankind's love. Love of/from God is holy because the source is naturally holy. Mankind's brand of love cannot be holy because the source is not naturally holy.)

Unlike God, who is a Spirit-THE Holy Spirit, man is carnal and made of flesh from the elements of the earth.

• The first man is of the earth, earthy;... 1 Corinthians 15:47.

Yes. We must understand and remember that the will of God is the supreme law of the universe and all of creation because He made it and everything possible. Therefore, He reveals Himself to us according to His will, as He decides. Thus, all aspects of God's persona that He chooses to use as a revelation of Himself are God, and each is part of the one and only Holy Spirit (the "Spirit") throughout time and the universe forever.

In the most literal sense, God the Father gives of Himself in love because He is literally the best of everything conceivable. Otherwise, He is not God. Therefore, the best gifts are of God and from Himself-the one and only Holy Spirit.

• 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? Luke 11:13.
• If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him? Matthew 7:11.

Per His will, like a true loving Father, God reveals Himself to us in three ways. The Bible tells us the three revelations of God, the Holy Spirit, as personas and presentations, so that we may come to know Him, from both:

1. The perspective of heaven (the personas); and
2. The perspective of earth (the presentations). 

When we compare the two perspectives, we find the great revelation of Himself that He intended, according to His will (i.e., in the manner He decides).

The Father chose certain presentations of His own persona so that we could know Him on earth if we chose to learn of Him, so let's do that! 

• Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. Matthew 11:29.
• It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me. John 6:45.
• Draw nigh to God, and he will draw nigh to you... James 4:8.

We start with His Word. Of course, the Word of God is God-the Holy Spirit. 

• In the beginning was the Word, and the Word was with God, and the Word was God. John 1:1.

Thus, how does He present Himself according to His Word; How did He describe Himself?

From the perspective of heaven, the Spirit realm (the personas of "God in heaven"), the scriptures say:

• For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. 1 John 5:7.

The Holy Spirit (God) is individually and collectively the Father, the Word, and the Holy Ghost. Each of the three personas are God-THE Holy Spirit because He is one Spirit, (see Ephesians 4:4, above). Think of an apple pie divided into three large pieces. The whole pie is the apple pie, and each piece is apple pie.  

From the perspective of earth, the physical realm (the presentations of "God with us on earth"), the Father said:

• Behold my servant, whom I have chosen; my beloved, in whom my soul is well pleased: I will put my spirit upon him, and he shall shew judgment to the Gentiles. Isaiah 42:1 and Matthew 12:18. 

The Father said He has a servant, a soul, and a spirit (lowercase "s" intended) by which we can know Him on earth. For now, think of spirit as truth. 

When we hold Him at His Word and match the three personas of God in the Spirit realm where heaven is His home, to the three presentations of God here on earth in the physical human realm of our home, we discover the pathway to Him and heaven just as He planned.

"God in heaven" (i.e., the personas of God in the Spirit):

• For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. 1 John 5:7. 

matched with

"God on earth" (i.e., the presentations of God in the physical earth):

• Behold my servant, whom I have chosen; my beloved, in whom my soul is well pleased: I will put my spirit upon him, and he shall shew judgment to the Gentiles. Isaiah 42:1 and Matthew 12:18. 

gives us this result:

• The Father = the soul (life) of God. 

He is THE almighty and great "I am". To us, He exists according to His will because He is God. Thus, we come to know the Father as the soul of God as the Father's will (according to His will) because He is God and the Father (creator/originator) of everything. 

• The Word = the servant (body) of the Father.

Whatever the Father says is a statement of His will and is or shall become proving His Word is part of Him, God. The bible says, "In the beginning was the Word, and the Word was with God, and the Word was God...And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth." John 1:1 and 14.

As discussed below in the context of His only begotten son, Jesus, there are then two contexts we MUST embrace. The only begotten son of the Father, is both:

1. The son of God in the Spirit-the Word as His persona; and 
2. The son of man in the flesh-the servant as His representation.

(Jesus is collectively and individually God in heaven and His servant on earth, as explained in detail below. See also, Isaiah 42:1 and Matthew 12:18 above.)

• The Holy Ghost = the spirit (truth) of the Father. 

Not surprisingly, the Father's truth is also called the "Spirit of Truth" because He is absolute truth. The Spirit of Truth (Holy Ghost) bears witness to the Father's Word and evidences the Father's will in power because God is absolutely, prophetically, truthful. The Spirit of Truth (the Holy Ghost) teaches us all things, reminds us of what Jesus said, quickens our mortal bodies, and much more. See John 14:17, 15:26, 16:13, 1 John 4:6, and Romans 8:8, for starters.  

Yes.

• And God said, Let us make man in our image, after our likeness: Genesis 1:26.

The plural reference to "us" acknowledges the fact He regards Himself as a trinity of personas: the Father Himself, His Word (whatever He says), and His Truth. God is also a trinity of presentations (servant/body, soul, and spirit) for man's recognition of his likeness to Him as explained in detail below.

Of course, God is eternal. The Father is eternal, His Word is eternal, and His Spirit of Truth (the Holy Ghost) is eternal. Therefore, mankind must also be eternal in some way in order for us to be created in His image and likeness.

In the image of God, mankind has a body (his servant), a soul (life in him), and a spirit (truth in him). All people have a spirit contained within a living soul and housed within a servant-their body. 

• ...and man became a living soul. Genesis 2:7.
• And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. 1 Thessalonians 5:23. 

In the likeness of God the Father, the soul of God, man's soul is eternal even though our earthly body is perishable like a piece of fruit. 

• And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell. Matthew 10:28.
• He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death. Revelation 2:11.
• And death and hell were cast into the lake of fire. This is the second death. Revelation 20:14.
• But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death. Revelation 21:8.

The soul of every person is the life that is given to them as a possession.

• In your patience possess ye your souls. Luke 21:19.

Thus, each of us is our own god because we are given control over our own eternal destiny.

• ...Is it not written in your law, I said, Ye are gods? John 10:34.
• I have said, Ye are gods;... Psalm 82:6.

To appreciate who and what Jesus is as the first and only begotten human child of the Father (God), we must know the "nature" of the parents always determines the nature of their offspring. For example, zebras (animals) are born from zebras as animals, sparrows (birds) from sparrows as birds, perch (fish) from perch as fish, and people (humans) from people as humans. Being born of God means being born of the Spirit. 

• That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. John 3:6.

Jesus was born a human child (mankind) and God the Father's son (Spirit). Jesus is the ONE AND ONLY begotten (human-birthed) son of God the Father! He is part God (Spirit) and man (flesh).

Recall that every person has a body (servant), soul (life), and spirit (truth). Accordingly, Jesus has a body, soul, and spirit. 

Jesus received His human body from His human parent, Mary, His mother. Recall, "That which is born of the flesh is flesh;..." John 3:6a.

Jesus was conceived in Mary, His mother, by the Holy Ghost, the Spirit of Truth, but without human contact because the Spirit is not flesh.

• Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost. Matthew 1:18.
• But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost. Matthew 1:20.

Thus, Jesus was also the son of God by the power of the Spirit of Truth, the Holy Ghost.  

• ...that which is born of the Spirit is spirit. John 3:6b.

Remember, the Father's spirit (truth) IS the Holy Ghost. The Word of God foretold (prophesied) the coming of Christ Jesus, born of a woman (a son of man) and born of God (a son of God).

Recall that every person, including Jesus, has a body (servant), soul (life), and spirit (truth); and, "that which is born of the flesh is flesh, and that which is born of the Spirit is spirit", see John 3:6 above.

From the moment of conception, Jesus's spirit (truth in Him) was different from ours. Jesus received His spirit (truth in Him) from God as the "offspring" of the Father (Spirit). Recall that the Father's Word is His servant and His offspring in the Spirit because it originates from Him. See Isaiah 42:1 and Matthew 12:18, above. 

God the Father presented His persona, His Word, the Word of God as God (John 1:1), inside of that human named Jesus. In the context of the Spirit, the Word of God is the offspring (issue) from the Father Himself, just like our words are the offspring (issue) from us when we speak. Therefore, the spirit (truth) of Jesus IS the Word of God from the Father. The Word of God in Jesus is what made Him Emmanuel, "God with us" (Matthew 1:23, see also Isaiah 7:14). Jesus knew who He was from the inside out. He knew the God part of Him was the Word inside Him.

The Word (the Holy Spirit, or simply the Spirit) in Him is the very reason why Jesus IS the only begotten son of God from birth, and only He is the doorway to God.

• In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink. 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 7:37-39.

Simply stated, the Word of God IS the spirit/Spirit (man's truth/God's truth) inside a man.

• In the beginning was the Word, and the Word was with God, and the Word was God...And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. John 1:1 and 1:14.

The phrase "the Word was made flesh" (John 1:14 above) means the Word (Spirit) was given a very important flesh suit to dwell within because that which is born of the flesh is flesh and that which is born of the Spirit is spirit. John 3:6. Of course, Jesus was born a living soul like all of us. 

Therefore, Jesus was born mankind (flesh) and Godkind (the Holy Spirit). More specifically, Jesus is the servant of God because the Word of God is Him from the beginning. 

Jesus is both the Son of God and the Son of Man, and only He can proclaim that truth everywhere. The Word of God gives the believer the power to become a child of God in the Spirit, starting with the Word, the same way Jesus had the Word (Spirit) in Him as the first child of God. As discussed later, this is why we who are "born again" of the Spirit are said to comprise and be alive "in Him" as the body of Christ Jesus today on earth.

God the Father wants us to know Him. We come to know Him by learning His Word. His Word is THE door to the Spirit. Jesus, the begotten son with the Word of God inside Him, said:

• Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. Matthew 11:29.
• It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me. John 6:45.

No. There can be no faith in something that has already happened because it is a fact. Whatever happened are facts to be believed.

For example, the death of Jesus on the cross and His resurrection unto life thereafter are well-documented events of human history! In fact, most of the original disciples, more than five hundred (500) miscellaneous people who knew Jesus, and Paul (the guy who authored almost 2/3 of the New Testament) all saw Him alive days after His lifeless body was taken off the cross He was nailed to and buried in a tomb. 

• For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures: And that he was seen of Cephas, then of the twelve: After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep. After that, he was seen of James; then of all the apostles. And last of all he was seen of me also, as of one born out of due time. 1 Corinthians 15:3-8.  

Therefore, the events of Jesus' death and resurrection are facts to be believed. When we believe the facts about the crucifixion and resurrection of Jesus and the promise of salvation Jesus gave us, we have the “power to become” God's sons (children) by adoption through faith in the Father's Word. However, faith is belief put into action, i.e., conduct (action) in reliance on the belief. Confessing (admitting) sin and repentance from sin are the actions (conduct) of faith needed to be born again and saved when our body dies. Both, confession and repentance are required to become born again of the Spirit (saved) and live forever.
