The Holy Spirit.

Is a spirit an ordinary force or a personality? 

"And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; Even THE SPIRIT OF TRUTH;..." (John 14:16).

In our physical world, immaterial beings are called spirits. They have the physical characteristics of a living creature, but are not tangible. They are like "pictures in motion" or motion picture. Therefore, ALL IMMATERIAL BEINGS ARE SPIRITS WITH A FORCE (or a form of knowledge), and come to think of it, if you are born-again, you have a new spirit within you! There are two kinds and three categories of spirits :- 

Kind 1 Type 1- The Holy Spirit: the Person and Spirit of God.
Kind 2 Type 2- The Angelic spirits: Ministering angels of light.
Kind 2 Type 3- The Evil spirits: Desecrators and rulers of "the world" of darkness.

NEVER LET ANYBODY TELL YOU THE HOLY SPIRIT IS NOTHING BUT A FORCE. THE HOLY SPIRIT IS THE PERSONALITY OF GOD; THE MOTION PICTURE OF GOD IN OUR HEARTS AND MINDS. 

He fully manifested Himself in/through the Son of God, Christ Jesus. He is The ONLY One, in the physical absence of Christ, that knows God, and can train and make us become the sons of God, the gods of this earth. He is The One "...whom THE WORLD cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you." (John 14:17).

The basics of spirits.

Spirits are a different form of life to that of the human body. They are intangible and can't be physically handled. They interrelate with the human mind and fills the heart with their personality - life or death.  

There categories of spirits: the Holy Spirit for making life; the angels for ministering life; and devils for taking away life. The only life giving Spirit is the Holy Spirit. Angels carries aspects of this Life/Breath of God in form of light, while the devils takes away aspects of this Life, resulting in death. 

[Note: Angels don't indwell the heart, they are not The Life/Breath. The Holy Spirit is The Life/Breath that is in The Bread/Word of Life of The gospel of Christ. (Please read John 6:63, 20:22; Gen 2:7)].
