Any serious reflection on the greatness of God and His boundless mercy will lead to the realization that there is no end and no purpose to His light.
This light also remains unchanged and constant in its emanation from the Divine and it never imposes a limit in any of its manifestations.
In contrast to the numerical, or any other, infinity, with its severe limitations in all directions but one, the infinite light of God has no limit in any direction or form.
