The central reality for Christians is the personal, unalterable, persevering commitment that God makes to us. Perseverance is not the result of our determination, it is the result of God’s faithfulness. We survive in the way of faith not because we have extraordinary stamina but because God is righteous. Christian discipleship is a process of paying more and more attention to God’s righteousness and less and less attention to our own; finding the meaning of our lives not by probing our moods and motives and morals but by believing in God’s will and purposes; making a map of the faithfulness of God, not charting the rise and fall of our enthusiasm.
