Not everyone cares to talk about the Holy Spirit all that much, but i feel we must. As a community of believers, as Christians, as the burning light of God in this world, we must speak not only of God and Christ, but the power that drives us, that fuels us, that energetically sets our hearts aflame and leads us.
I'm not sure the reason the Christian community overlooks the Holy Spirit. It could be due to fear of blasphemy, as blasphemy against the Spirit is said to be the only unforgivable sin.
But think thusly; if speaking ill of your father would get you kicked out of the house and left on the streets, would you do it? Of course not. Would you not talk about them for fear of it? Unlikely. You would act as though they were your parents.
Why then, when speaking about the infinitely merciful and gracious God, do we speak of His Spirit with such reluctance? We should speak of the Holy Spirit all the more, that we have not been kicked out of the house for all the other wrongs we've committed against Him!
Now, the Holy Spirit is an "all-consuming" Fire. He's not "somewhat-consuming," or even "mostly-consuming." He is "all-consuming." Beginning to end, He is there.
We speak of God, of Christ, of salvation, even of the gifts of the Spirit, but we do not speak enough -could not speak enough!- of the Holy Spirit. Speaking of the gifts but not of the source is like saying "I got a guitar," but not saying it was from your friend. It's a massive overlook.
He wants us to give Him glory, but the accreditation is often left out, or worse, given unto ourselves (especially when speaking of words of knowledge or wisdom, or of faith or of love, which are gifts of the Spirit). This attitude is a disgrace. All He wants is for us to recognize Him and say "He gave me this guitar--and He's giving me lessons on it, too."
Again i say, He is an all-consuming Fire. He burns within us passionately, and with the same passion and power as that which was in the Word that said "Let there be light!"
That kind of power is frightening. It can create or destroy with but a single word. That is where the fear of God flows from; not in a terror that pushes us away, but a fear of being on the wrong side of the power behind creation (that is often initially what drives us to Him, but love does not come from being "scared to" something). He does not align Himself with you; you align yourself with Him. And we don't always fear being on the wrong side of this force, you fear being away from this force. This fear is a dependency. And it develops into love; just as a bear cub is terrified of being away from its mother, we should be infinitely more terrified of being separated from the Holy Spirit.
The Holy Spirit is not some strange, shy thing. He is bold. He is perhaps the boldest characteristic of God.
God reigns. Christ atones. The Holy Spirit links the two together inside of us.
I say He is bold because it is the characteristic of God that makes Him real to us. Faith is a gift of the Spirit.
It's bold because it drives us to be like Christ, it drives us to love God, and it drives us to live for God. Whether or not we give this credit to the Holy Spirit, it is the reason we can preach, we can teach, we can love, we can hope, we can live.
The Holy Spirit is the invisible qualities of God mentioned in Romans 1, the undeniable aspect that makes us to be without excuse.
He's not something to tip-toe around while avoiding eye contact. It is the living force of God living within us, His Spirit, His "Breath of Life" given to Adam and Eve. It is what makes a son of man into a child of God, and transforms the dried-up bones scattering about the valley into a standing army of flesh-and-bone.
