To love our success more than God and our neighbor hardens the heart, making us less able to feel and to sense.
Timothy KellerAt the root of all our disobedience are particular ways in which we continue to seek control of our lives through systems of works-righteousness. The way to progress as a Christian is to continually repent and uproot these systems the same way we become Christians, namely by the vivid depiction (and re-depiction) of Christโs saving work for us, and the abandoning of self-trusting efforts to complete ourselves. We must go back again and again to the gospel of Christ-crucified, so that our hearts are more deeply gripped by the reality of what he did and who we are in him.
