The Holy Spirit:
His personality – John 16:7-15
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. And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
Of sin, because they believe not on me;
Of righteousness, because I go to my Father, and ye see me no more;
Of judgment, because the prince of this world is judged.
I have yet many things to say unto you, but ye cannot bear them now. 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.
He shall glorify me: for he shall receive of mine, and shall shew it unto you. All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you.
His deity – Acts 5:3-4
But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land?
Whiles it remained, was it not thine own? and after it was sold, was it not in thine own power? why hast thou conceived this thing in thine heart? thou hast not lied unto men, but unto God.
His work in each believer;
His baptism – I Corinthians 12:13
For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
His indwelling at the moment of regeneration – Romans 8:9
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
His filling – Ephesians 5:18
And be not drunk with wine, wherein is excess; but be filled with the Spirit;
His empowering for Christian life and service
That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;
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.
And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.
But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance: against such there is no law.
…let the word of Christ dwell (take up its life) in you richly…
