Not only is it perfect grace as contrasted with uncertainty and legal fitness, but the Father's conduct was the Son's place and the whole of it—He had no other. It is to be noticed that, in Luke 15, in the prodigal son, it is not Christ's meeting the claims of God's justice as a holy righteous Judge, but the divine favor and goodness, though He had the best robe on (Christ), a sign of that favor and love—fitness, but according to the Father's heart.
