“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 hidden with Christ in God’ (Colossians 3:1-3) means appreciating, rejoicing, and resting in what Jesus has done for you. It entails joyful worship, a sense of God’s reality in prayer.
Jesus must become more beautiful to your imagination, more attractive to your heart, than your idol. That is what will replace your counterfeit gods. If you uproot the idol and fail to ‘plant’ the love of Christ in its place, the idol will grow back.”
–Timothy J. Keller, Counterfeit Gods (New York: Dutton, 2009), 171-172.
