“Spirit” is from the Greek word pneuma [# 4151 in Strong’s]. It means “a movement of air…of the wind…” Since God is an invisible Spirit, worship of Him must come out of a spirit nature. It takes a spirit to worship the Spirit.
After all, if we have been truly “born again,” we are spirit. “That which is born of the Spirit is spirit” (John 3: 6-8). If you are born of the Spirit, then you are a spirit and not the earthly body you see in the mirror. Since we are spirit, we merely reside now in an earthen body of flesh. Christ calls those that are born of the Spirit—a spirit. This knowledge helps us worship “in spirit.”
Moreover, He likens us to an invisible wind that blows across the earth. We are free like the wind is free, for we are a spirit born out of the loins of our Father, who is the Spirit of truth. We are like the wind, free to love others, not bound by the physical restraints imposed by worldly tradition peddlers. We are free to love with the soft breezes of compassion and mercy, free as the wind to soothe those who sweat in turmoil, who now writhe in the darkness of this cruel world’s overseer. And there is no law against this wind of love that now inhabits our frail bodies, that now is exhaled through us, His lungs and mouth.
“So is every one that is born of the Spirit.” And because each seed bears its own kind, we as new spiritual creatures in Christ have an “earnest” of His Spirit within, and He now breathes out of our mouths the word of God. That is part of true “worship.” It is submitting our bodies to be used by the Spirit of God within us to utter His words of life to others. It is allowing the Spirit to minister through us. And His word through His children’s mouth “will not return unto [Him] void, but it shall accomplish that which He pleases” (Isa. 55: 11). Kenneth Wayne Hancock
