"Setting the mind and heart on things above" where "your life is hid with Christ in God" means appreciation, 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.
