The Examination of Creation Shows the Goodness of the Creator
The way in which man can most readily arrive at a knowledge of God is by a critical study of the works of creation in general, and of man in particular.
The result of this examination will be to show you that the Creator is not only wise but infinitely good and beneficent, and that His goodness is over all His works.
