Charles Ellicott Commentary Luke 15:31

"And he said unto him, Son, thou art ever with me, and all that is mine is thine." — Luke 15:31 (ASV)

Son, you are ever with me.—As applied to the Pharisees in its primary application, or to others like the Pharisees in its secondary application, it appears at first sight as if the words were spoken from their own point of view, their own self-appreciation, and were therefore ironical. We need not, however, interpret them this way. The words were literally true of the Pharisees, of Israel as a nation, and of all who reproduce the Pharisaic character.

All outward gifts that God could bestow—the covenants, the law, and the promises, outward ordinances of worship, and the instruction of wise men and scribes—these had all been given to Israel, as similar blessings are offered now to all members of the visible Church of Christ, the great family of God.

All that was lacking was the power to use these things rightly, as the Father wills, and therefore to enjoy them.

All that I have is yours.—More literally, all mine is yours.
