Charles Spurgeon Commentary Luke 15:18-19

"I will arise and go to my father, and will say unto him, Father, I have sinned against heaven, and in thy sight: I am no more worthy to be called your son: make me as one of thy hired servants." — Luke 15:18-19 (ASV)

I will arise and go to my father, and will say unto him, Father, I have sinned against heaven, and before thee, and am no more worthy to be called thy son: make me as one of thy hired servants.

You notice that this last part of the prayer he never prayed; for it was stopped by his father's love. There was a legalism about it naturally suggested by his own despair, but it was not such as his father would tolerate.
