Work often requires self-forgetfulness, that one lose himself in a cause, in the reality of the task at hand. How then does one “Pray without ceasing (1 Thessalonians 5:17)?”
Morning prayer “reaches beyond its set time to include the whole day . . . every word, every work, every labor becomes a prayer; not in the unreal sense of a constant turning away from the task that must be done, but in doing all in the name of the Lord Jesus (Colossians 3:17).”*
Dietrich Bonhoeffer, Life Together, p. 70-71.
