Luke 15:21 - Ellicott's Commentary On The Whole Bible

Father, I have sinned against heaven. — The iteration of the self-same words comes to us with a wonderful power and pathos. The contrite soul does not play with its contrition, or seek to vary its expression. But the change is as suggestive as the repetition. Now that he has seen his father, he cannot bring himself to say again, “Make me as one of thy hired servants.” That had been a natural and right wish before; it would savour of unreality and hypocrisy now. This also has its analogue in the history of true penitents. In the first stirrings of contrition they stand afar off, and as they confess their sins hardly dare to hope for restoration to the blessedness of sons; but when they have felt the Father’s kiss, though still confessing that they are unworthy to be called sons, they cannot be satisfied with anything less than sonship.
