“Should we worship the Holy Spirit?”
Long before the Word was made flesh, the Holy Spirit was present in the world and active on behalf of the Godhead. We find him in the second verse of Genesis, the fourth-last verse of Revelation, and everywhere in between. He is mentioned approximately 100 times in the Old Testament and well over 200 in the New. It has been demonstrated from the scriptures that he possesses the same attributes as both Father and Son.* His significance to us can hardly be overstated, since without him we would not have the written Word at all.
So it’s a good question: Why not worship the Holy Spirit? He’s certainly worthy of our worship.
