It is only by living completely in this world that one learns to live by faith. One must completely abandon any attempts to make anything of oneself, whether it by saint or converted sinner, or churchman, righteous man or unrighteous man, sick man or healthy one. By this worldliness. I mean living unreservedly in life duties, problems, success, and failures, experiences and perplexities. In so doing we completely throw ourselves into the arms of God. Taking seriously not our own suffering but those of God in the world watching with Christ in Gethsemane. That I think is faith. That is how one becomes a man and a Christian.
- Dietrich Bonhoeffer
