What does the Bible say about the spirituality of God?

In John 4:24, Jesus declares, 'God is a spirit: and they that worship him must worship him in spirit and in truth.' This fundamental truth underscores the nature of God, emphasizing that He is not confined to a physical body but exists as a spiritual being. The implication of this is profound—our worship should engage our spirit and must align with truth. The spiritual nature of God requires that any worship directed towards Him is not merely ritualistic or formal, but rooted in a genuine, heartfelt response to His divine character and revelation.
