God is a spirit,.... Or "the Spirit is God"; a divine person, possessed of all divine perfections, as appears from his names, works, and worship ascribed unto him; See Gill on "Joh 4:23"; though the Arabic and Persic versions, and others, read as we do, "God is a spirit"; that is, God, Father, Son, and Holy Ghost: for taking the words in this light, not one of the persons is to be understood exclusive of the other; for this description, or definition, agrees with each of them, and they are all the object of worship, and to be worshipped in a true and spiritual manner.
God is a spirit, and not a body, or a corporeal substance: the nature and essence of God is like a spirit, simple and uncompounded, not made up of parts; nor is it divisible; nor does it admit of any change and alteration.
