What does God's word have to say about those who serve and worship created things (images, statues, relics, etc.) instead of the one true Creator God?
Our God is in the heavens;
he does all that he pleases.
Their idols are silver and gold,
the work of human hands.
They have mouths, but do not speak;
eyes, but do not see.
They have ears, but do not hear;
noses, but do not smell.
They have hands, but do not feel;
feet, but do not walk;
and they do not make a sound in their throat.
Those who make them become like them;
so do all who trust in them.
O Israel, trust in the LORD!
He is their help and their shield.
O house of Aaron, trust in the LORD!
He is their help and their shield.
You who fear the LORD, trust in the LORD! - Psalm 115:3-11a
