“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.”

STRONG’S CONCORDANCE G4151
Original Word: πνεῦμα
Transliteration: pneûma
Phonetic Spelling: pnyoo’-mah
[πνεῦμα] from G4154; a current of air, i.e. breath (blast) or a breeze; by analogy or figuratively, a spirit, i.e. (human) the rational soul, (by implication) vital principle, mental disposition, etc., or (superhuman) an angel, demon, or (divine) God, Christ’s spirit, the Holy Spirit Compare G5590.
There is another important aspect of the definition of “spirit” and that is “mental disposition” or mind/mindset. The breath aspect is as in the exhaling of breath i.e. “blast of air”. When we speak or sing songs of praise it is when we are on the exhaling of breath. Try talking or singing while inhaling. Most people speak their minds or at least speak what is on their minds. Doesn’t this paint a portrait of one’s character i.e. one’s mental disposition or mindset? When we accept the sacred spirit (breath), we not only accept the “Word of God” but His “mental disposition” as part of the “vital principal as well.
