Jamieson, Fausset and Brown on Luke 15:18

18. I will arise and go to my FATHER--The change has come at last, and what a change!--couched in terms of such exquisite simplicity and power as if expressly framed for all heart-broken penitents.

Father, &c.--Mark the term. Though "no more worthy to be called his son," the prodigal sinner is taught to claim the defiled, but still existing relationship, asking not to be made a servant, but remaining a son to be made "as a servant," willing to take the lowest place and do the meanest work. Ah! and is it come to this? Once it was, "Any place rather than home." Now, "Oh, that home! Could I but dare to hope that the door of it would not be closed against me, how gladly would I take any place and do any worK, happy only to be there at all." Well, that is conversion--nothing absolutely new, yet all new; old familiar things seen in a new light and for the first time as realities of overwhelming magnitude and power. How this is brought about the parable says not. (We have that abundantly elsewhere, Php 2:13, &c.). Its one object is to paint the welcome home of the greatest sinners, when (no matter for the present how) they "arise and go to their Father."
