Pagans do not see the folly of idol-worship because God has blinded their minds (cf. Isaiah 6:9-10; Isaiah 29:14). Having chosen to refuse the revelation of God that He has given them in nature, He makes it impossible for them to see the truth (cf. Romans 1:18-24; 2 Thessalonians 2:10-11). If this were not the case, they would understand and abandon their practices, since it is so clear that Prayer of Manasseh -made gods are not deity. [source][source][source]
Modern man is in the same position as his ancient counterpart. Westerners do not cut down trees and fashion blocks of wood into idols that we put on shelves in our houses and bow down to. But we work long hours to be able to purchase some Prayer of Manasseh -made object (of clothing, jewelry, transportation, communication, entertainment, etc.) that we then hope will provide us with what only God can provide. Tragically, we do not even view this as idolatry because we, too, are blind. [source][source][source]
