He is God's Spirit, the Spirit of Truth, the Comforter, He who bears witness to the Truth, the Spirit of prophecy and testimony of Jesus Christ. Here's some verses...
John 14:16-27[SUP]
16 [/SUP]And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
[SUP]
17 [/SUP]Even 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 shall be in you.
[SUP]
18 [/SUP]I will not leave you comfortless: I will come to you.
[SUP]
19 [/SUP]Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.
[SUP]
20 [/SUP]At that day ye shall know that I am in my Father, and ye in me, and I in you.
[SUP]
21 [/SUP]He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
[SUP]
22 [/SUP]Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world?
[SUP]
23 [/SUP]Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
[SUP]
24 [/SUP]He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.
[SUP]
25 [/SUP]These things have I spoken unto you, being yet present with you.
[SUP]
26 [/SUP]But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
[SUP]
27 [/SUP]Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid."
Not only does He guide us into all Truth, but He also gives us the ability t bring forth the fruits shown below....
Galatians 5:22-23 [SUP]
"[/SUP]But
the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
[SUP]
23 [/SUP]Meekness, temperance: against such there is no law."
But He also does this in the Lord's disciples....
John 16:7-16
[SUP]
7 [/SUP]Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
[SUP]
8 [/SUP]And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
[SUP]
9 [/SUP]Of sin, because they believe not on me;
[SUP]
10 [/SUP]Of righteousness, because I go to my Father, and ye see me no more;
[SUP]
11 [/SUP]Of judgment, because the prince of this world is judged.
[SUP]
12 [/SUP]I have yet many things to say unto you, but ye cannot bear them now.
[SUP]
13 [/SUP]Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
[SUP]
14 [/SUP]He shall glorify me: for he shall receive of mine, and shall shew it unto you.
[SUP]
15 [/SUP]All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you.
[SUP]
16 [/SUP]A little while, and ye shall not see me: and again, a little while, and ye shall see me, because I go to the Father.
And there are also the gifts of the Spirit as well.
1 Corinthians 12:7-11
[SUP]
7 [/SUP]But the manifestation of the Spirit is given to every man to profit withal.
[SUP]
8 [/SUP]For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit;
[SUP]
9 [/SUP]To another faith by the same Spirit; to another the gifts of healing by the same Spirit;
[SUP]
10 [/SUP]To another the working of miracles; to another prophecy; to another discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues:
[SUP]
11 [/SUP]But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
