A love affair of the heart...

For above all else, the Christian life is a love affair of the heart. It cannot be lived primarily as a set of principles or ethics. It cannot be managed with steps and programs. It cannot be lived exclusively as a moral code leading to righteousness. In response to a religious expert who asked him what he must do to obtain real life, Jesus asked a question in return:
“What is written in the Law? . . . How do you read it?” He answered: “‘Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind’; and, ‘Love your neighbor as yourself.’”“You have answered correctly,” Jesus replied. “Do this and you will live.” (Luke 10:26–28, emphasis added)
The truth of the gospel is intended to free us to love God and others with our whole heart. When we ignore this heart aspect of our faith and try to live out our religion solely as correct doctrine or ethics, our passion is crippled, or perverted, and the divorce of our soul from the heart purposes of God toward us is deepened.
