Hey all--Great thread....I have done a lot of study in pneumatology and have to say it's a subject that really invokes a lot of response in me, so I'll have a lot to say but probably will exceed 24 K if I posted everything so I'll post some...
John 14:16-17, 26
16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
17 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.
26 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.
KJV
So we see from the surface that the work of the Spirit is teach us all things, and bring all things to our rememberance....People often ask me how I can remember the scriptures I do when I'm preaching...Some of them, if you asked me to say them I couldn't, because it was the Spirit that brought them to my rememberance.
The Greek word for the word Comforter in v. 16 and 26 is the word paraclete...The Amplified transalation does just that and amplifies it and gives us the 7-fold meaning of the word.
Comforter, Counselor, Helper, Intercessor, Adovocate, Strengthener, and Standby.
John 16:7-15
7 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.
8 And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
9 Of sin, because they believe not on me;
10 Of righteousness, because I go to my Father, and ye see me no more;
11 Of judgment, because the prince of this world is judged.
12 I have yet many things to say unto you, but ye cannot bear them now.
13 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.
14 He shall glorify me: for he shall receive of mine, and shall shew it unto you.
15 All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you.
KJV
So we see from the text that He reproves the world of sin....I've prayed before for the convicting power of the Holy Spirit to follow a person until they came to Christ.
He guides us into all truth and shows us things to come. What does that mean? He leads us in the paths of righteousness. He teaches us from the Word.
He shows us what we have through Christ. He glorifies Christ.
Acts 1:8
8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
KJV
After we've recieved the Spirit power. Power for what? Power to be witnesses unto the uttermost part of the earth!
We see in
Acts 9:31 that the churches were walking in the comfort of the Holy Ghost.
We see in
Acts 20:23 that the Holy Ghost showed Paul things to come.
We see in
Acts 13:2 and 20:28, He calls people to the work of the ministry...Rather to say He CONFIRMS in people the call of ministry because it says in
Ephesians 3:8 in talking about Jesus "Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men".
Romans 5:5
5 And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.
KJV
So the Spirit has given us the ability to love as God loves.
Romans 8:14-16
14 For as many as are led by the Spirit of God, they are the sons of God.
15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16 The Spirit itself beareth witness with our spirit, that we are the children of God:
KJV
The Spirit confirms that we are sons of God. He leads us.
Romans 9:1
9:1 I say the truth in Christ, I lie not, my conscience also bearing me witness in the Holy Ghost
KJV
The Spirit helps our conscience and guides us to help keep us out of sin and in righteousness and holiness.
1 Corinthians 2:9-12
9 But 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.
10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
11 For 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.
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
KJV
This is kind of rough to understand at first glance so let's look at some things. We read in Isaiah what is in v.9, but now that we've been born of the Spirit and He lives in us, He reveals those things that eye hath not seen nor ear heard, yes these deep things of God! Look at v. 11. "For what man knoweth the things of a man, save (except) for the spirit of man which is in him?" :elvis: Take our little friend here. Aside from God, no one knows him better than himself. No one knows his likes his dislikes his everything more than himself! So the verse goes on to say "even so the things of God knoweth no man, but the Spirit of God" THINK ABOUT THIS!!! NO one can know God better than God's own Spirit, SO God in order for us to know Him says I"m going to take ME and put ME in YOU!! The One that knows God the very best lives in you!!!

This is why Jesus said in
John 16:7 that is was good for Him to go. Even if Jesus was walking in our presence telling us all He could of the Kingdom of God, and righteousness and Holiness and on and on, this is better because the Spirit of God Himself lives on the inside of us so that we can know things!
In following verses in
1 Cor 13:13 we see that the Spirit helps teachers to teach as well as hearers to understand.
This is only one part of the Spirit's work, because it is one thing to be born of the Spirit, which all i've written involve, but it's another thing to be filled with the Spirit. There is MUCH more I could write if I included all the work of the Spirit after being filled.
If you are interested there is a new book available called The Spirit Within and the Spirit Upon. Probably available if you search for it at amazon....
