Luke 15:31

Son, thou art ever with me. — As applied to the Pharisees in its primary bearing, or to others like the Pharisees in its secondary, 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, so take them. The words were literally true of the Pharisees, of Israel as a nation, of all who reproduce the Pharisee temper. All outward gifts that God could bestow, the covenants and 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 like blessings are offered now to all members of the visible Church of Christ, the great family of God. All that was wanted was the power to use these things rightly, as the Father wills, and therefore to enjoy them.

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