How do we know that idols have no spiritual value?

The brazen serpent, initially used by God to heal, became an object of worship itself—a classic example of how spiritual significances can be lost when people attribute value to physical objects. King Hezekiah declared it 'Nehushtan,' or a piece of brass, illustrating that even items once used by God can lose their sanctity if they become focal points of idolatry. This perspective aligns with the teaching found in the New Testament as well, where we are reminded that Christ is our sole source of salvation and worship. This is demonstrated in John 14:6 where Jesus declares, 'I am the way, the truth, and the life.' Therefore, true believers recognize that placing hope or worship in physical objects is ultimately futile and detracts from the glory that is due to God alone.
