Write a persuasive essay on is divine illumination necessary for us to acquire knowledge of infallible truth?

Augustine emphasized the role of divine illumination in our thought, in which God gives us insight into the truth of our knowledge. Does this mean that God gives us knowledge that is certain? Is the truth of things as they are in the mind or in their own nature—given that both are changeable—sufficient for the soul to have knowledge that is certain, or must the soul reach things as they are in the “eternal art,” i.e. is divine illumination necessary for us to acquire knowledge of infallible truth? Is this divine illumination of the intellect sufficient on its own, without the senses?
