What does it mean that God is spirit?

In John 4, we learn that God is spirit, distinguishing Him from His creation. This truth implies that God is not limited by physical form and cannot be worshiped through tangible objects or rituals. Attempting to understand God through physical means or images undermines His spiritual nature and leads to idolatry. True comprehension of God requires spiritual insight granted by the Holy Spirit, enabling believers to worship Him accurately and understanding His character as revealed in Scripture.
