Idolatry is not just a failure to obey God, it is a setting of the whole heart on something besides God. This cannot be remedied only by repenting that you have an idol, or using willpower to try to live differently. Turning from idols is not less than those two things, but it is also far more. “Setting the mind and heart on things above” where “your life is hid with Christ in God” (Colossians 3:1-3) means appreciation, rejoicing, and resting in what Jesus has done for you.
