Lukas 5:8

5:8 But when Simon Peter saw it, he fell down at Jesus’ knees, saying, “Go away from me, Lord, ¹  for I am a sinful man!” ² 

Lukas 17:4

17:4 Even if he sins against you seven times in a day, and seven times returns to you saying, ‘I repent,’ you must forgive ³  him.”

[5:8]  ¹ sn Lord is a term of high respect in this context. God’s presence in the work of Jesus makes Peter recognize his authority. This vocative is common in Luke (20 times), but does not yet have its full confessional force.

[5:8]  ² sn Peter was intimidated that someone who was obviously working with divine backing was in his presence (“Go away from me”). He feared his sinfulness might lead to judgment, but Jesus would show him otherwise.

[17:4]  ³ sn You must forgive him. Forgiveness is to be readily given and not withheld. In a community that is to have restored relationships, grudges are not beneficial.
