Dietrich Bonhoeffer Quote

Who am I? this or the other?
Am I one person today and tomorrow another?
Am I both at once? A hypocrite before others,
and before myself a contemptible woebegone weakling?
Or is something within me still like a beaten army fleeing
in disorder from a victory already achieved?
Who am I? They mock me, these lonely questions of mine.
Whoever I am, Thou knowest, O God, I am thine!
