The Holy spirit, Holy ghost, comforter, counselor, teacher, guide, spirit of God. The Holy spirit is not a force that we can harness, the Holy spirit is a being, as a person (able to feel emotion), referred to as He, and is part of the triune God; Father, Son, and Holy spirit.
John 14:26 but the comforter, which is the Holy ghost, which the father will send in my name, HE shall teach you all things, and bring all things to remembrance, whatsoever I have said unto you.

The Holy Spirit Is Part of the Trinity:
Genesis 1:1 ... In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the spirit of God moved upon the face of the waters.
John 1:1 In the beginning was the Word, and the Word was with God, and the word was God. The same was in the beginning with God. All things were made by him; and without him was not anything made that was made.

Matthew 3:16-17 And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him: And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.
Note the parallel between what Jesus speaks, and what the Holy spirit speaks:
John 16:23 (Referring to the Holy Spirit) ... for he shall not speak of himself; but whatsoever he shall hear, that shall he speak;
John 12:49 (Referring to Jesus) For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak.
The Holy spirit comforts, teaches, guides, testifies of the truth, reproves, convicts, communicates, glorifies God, empowers, transforms, inspires, seals, sanctifies, calls, fills, reveals, resurrects, prophecies, prays, instructs, produces fruit, seeks the greater good, and abides in those who belong to Christ.

Acts 8:35-38 Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus. And as they went on their way, they came unto a certain water: and the eunuch said, see here is water; what doth hinder me to be baptized? And Philip said, if thou believe with all thine heart, though may. And he answered and said, I believe that Jesus Christ is the son of God. And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him.
We cannot live the christian life without being filled with the Holy Spirit. The Holy spirit provides the power, peace, provision, passion, purity, holiness, wholeness, wisdom, discipline, desire, discernment, direction, counsel, comfort, correction, conviction, courage necessary to follow Jesus Christ. If we do not have the Holy Spirit living within us, we do not belong to Christ. By the Holy Spirit we mortify our flesh, obliterate our sinful desires, as He (The Holy Spirit) produces Godly character within us through the fruit of the spirit.
Matthew 27:18-20 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.

Amen.

Romans 8:12-14 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. For as many as are led by the Spirit of God, they are the sons of God.
Galatians 5:22 But the fruit of the Spirit is love, joy, peace, long-suffering, gentleness, goodness, faithfulness, kindness, and self control: against such there is no law. And they that are Christ's have crucified the flesh with the affections and lusts. If we live in the Spirit, let us also walk in the Spirit.

Luke 11:9-13 And I say unto you, ask, and it shall be given you; seek and ye shall find; knock, and it shall be opened unto you. For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. If a son shall ask bread of any of you that is a father, will he give him a stone? Or if he ask a fish, will he for a fish give him a serpent? Or if he shall ask for an egg, will he offer him a scorpion? If ye the, 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?
