As Quoted by A.W. Pink in The Attributes of God:
Whether God has decreed all things that ever come to pass or not, all that own the being of a God, own that He knows all things beforehand. Now, it is self-evident that if He knows all things beforehand, He either doth approve of them or doth not approve of them; that is, He either is willing they should be, or He is not willing they should be. But to will that they should be is to decree them. (Jonathan Edwards).
