Idolatry “steals” what rightfully belongs to God — i.e., glory.
Idolatry has no point, since idols cannot see, hear, think, talk, etc.
Idolatry represents God as lesser; no matter how impressive the idol, it would still pale in comparison to God, so idols are degrading.
Idolatry distracts the human heart from our ultimate affection, God.
Idolatry seeks help in the present/earthly rather than the unseen/heavenly.
Idolatry blurs the divide between Creator and created, since idols are made by human hands and made with earthly materials.
Idolatry fragments the Only God into a multitude of representations (i.e., polytheism via human imagination).
Idolatry rejects God’s Word, not merely disobedience of a commandment but a lack of trust that God is “Yahweh” — I AM, who cannot be created. (There was a time when an idol was “not” in existence.)
Idolatry destroys, as the imperfect become ultimate; the finite can never replace the infinite. (Example: If we idolize work, we eventually realize that work can never fulfill, but by that point, we’ve already suffered from idolizing work.)
Idolatry wastes life, robbing time, treasure, and talent.
