The Holy Spirit - the glorious third member of the Trinity - is no less God than the Father or the Son. Thus, to dishonor the Spirit is to dishonor God Himself. To abuse the Spirit’s name is to take God’s name in vain. To claim He is the one who empowers self-willed, whimsical, and unbiblical worship is to treat God with contempt. To turn the Spirit into a spectacle is to worship God in a way that He deplores.
