For as the Son says of the Father: “No man cometh to me except the Father draw him,” he might as well have said, except he move him. In like manner, also, could he have declared: “No man layeth down his life for my sake, except the Father move or draw him.” For since a man is drawn or moved by his will to that which he invariably chooses, it is not improper to say that God draws or moves him when he gives him this will. And in this drawing or impelling it is not to be understood that there is any constraint, but a free and grateful clinging to the holy will which has been given.
