How do we know that God is spirit?

In John 4:24, Jesus asserts, 'God is spirit.' This declaration speaks to the very essence and nature of God, signifying that He is incorporeal and not bound by physical limitations. Unlike humans or created entities, God does not possess flesh, bone, or any material form. This theological understanding of God as spirit is foundational to our worship; it challenges the tendency to conceive of God in human-like terms or physical representations. Recognizing God as spirit informs how we approach Him in worship, emphasizing the need for worship that is spiritual rather than material, engaging the heart and mind rather than mere external rituals.
