On Worship
From Created for Worship by Noel Due:
"…men and women are shaped morally by the objects they worship. Worship is not a static event, but a dynamic one. Engaging in false worship actually has an impact on the worshipper. To engage in idolatry affects the moral and spiritual condition of a person, or a nation. The character of the idol is borne in upon the soul of the society as much as it is borne in upon the soul of the individual.
Psalm 115:8: "Those who make [idols] become like them; so do all who trust in them."
