here are some verses for you to consider.
jesus says he will ask the father, and he will give the comforter, the holy spirit.
and that the holy spirit dwells with them and will be in them.
jesus then goes on to say that he himself will not leave them comfortless, he will come to them.
John 14
16And I will pray the Father, and he will give you another Comforter, that he may abide with you for ever; 17Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and will be in you.
18I will not leave you comfortless; I will come to you. 19Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also. 20At that day ye shall know that I am in my Father, and ye in me, and I in you.
jesus is the lord, and the lord is the holy spirit.
1Corinthian 12
3Wherefore I give you to understand, that no man speaking by the Spirit of God, calleth Jesus accursed: and that no man can say that Jesus is the Lord, but by the Holy Spirit.
2Coritnhians 3
17Now the Lord is the Spirit: and where the Spirit of the Lord is, there is liberty
1Cointhians 12
4Now there are diversities of gifts, but the same Spirit. 5And there are differences of administrations, but the same Lord. 6And there are diversities of operations, but it is the same God who worketh all in all. 7But the manifestation of the Spirit is given to every man for profit. 8For to one is given by the Spirit the word of wisdom; to another, the word of knowledge by the same Spirit;9To another, faith by the same Spirit; to another, the gifts of healing by the same Spirit; 10To another, the working of miracles; to another, prophecy; to another, discerning of spirits; to another, divers kinds of languages; to another, the interpretation of languages: 11But all these worketh that one and the same Spirit, dividing to every man severally as he will.
the spirit of god is gods presence.
Psalms 139
7Whither shall I go from thy spirit? or whither shall I flee from thy presence?
8If I ascend into heaven, thou art there: if I make my bed in hell, behold, thou art there.
9If I take the wings of the morning, and dwell in the uttermost parts of the sea;
10Even there shall thy hand lead me, and thy right hand shall hold me.
the holy spirit is a part of god, just as our own spirit is a part of us.
1Corinthians 2
9But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
10But God hath revealed them to us by his Spirit; for the Spirit searcheth all things, even the deep things of God. 11For 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.
the spirit is also called the finger of god and the power of god.
Matthew 12
28But if I cast out demons by the Spirit of God, then the kingdom of God is come to you.
Luke 11
20But if I with the finger of God cast out demons, no doubt the kingdom of God is come upon you.
