I find good reason to affirm the implications. If the first uncaused cause is not a cause from within the contingency system then it would have to be transcendent to the system, as a non-contingency, to produce the effect. Things are necessary, according as it is necessary for God to will them, since the necessity of the effect depends on the necessity of the cause.  It is not necessary that God should will anything except himself.  It is not therefore necessary for God to will that the world should always exist; but the world exists forasmuch as God wills it to exist, since the being of the world depends on the will of God, as its cause
