Why is understanding idolatry important for Christians?

Idolatry is a pervasive issue in human nature, as it reflects our propensity to create gods in our image rather than worshiping the one true God. Psalm 135:15-18 contrasts the lifeless idols made by man's hands with the living God who creates and sustains His people. This serves as a reminder that any notion of God that relies on human effort or imagination is fundamentally flawed and can lead to spiritual blindness. Recognizing idolatry helps Christians turn their hearts back to the true God, who is both alive and actively involved in redeeming His elect.
