“Remember, you are dust…” 
Being situated within the Lenten dynamic…
Luke 5:1ff tells how Jesus sent Simon (Peter) into the Deep to discover Jesus & the mission Jesus gave to him all stemming from his encounter with himself there.
[I present a more in-depth study of this passage in my book chapter eight, “In the Midst of Our Storms.”]
We can react to the uncovering of “what is weak & needs healing” with only remorse or guilt. Neither of these suffices for a full encounter with one’s capacity for betrayal. It’s the encounter with Jesus Christ that’s the key. He told Simon, “Don’t be afraid…” and then sent him on his mission as a disciple. Thus, recognition-turning away-encounter-mission is the full response to being sent to our depths.
