Upon Two Lights in a Room
What an amicable as well as amiable thing is light. For These two tapers enlighten the same room, do not shine with a divided or with a confounded, but with a united light as the optics do clearly demonstrate the distinct shadows which they cast: yet the eye which is benefited by both of them, to a more full and perfect discerning of its objects, cannot differentiate the rays and strictures that flow from them, or assign, which is the light that comes from one or the other.
Such I have sometimes thought is the harmony between the natural light of gifts and the supernatural grace meeting in the same person — though they be both differing the original, yet in the subject, in which they are seated, they shine not with a divided or confounded, but with a united light: For in their efflux and emanation so conspire, as that they greatly better him in whom they are conjoined and cast a mutual luster also upon each other: one being the gold which adorns the temple, and the other as the temple which sanctifies the gold.
Let no man therefore despise the light of gifts, as needless to the perfection of a Christian; nor yet so magnify it as to be injurious to the light of grace, no more than would put out one of his eyes as useless, because when he winks with one he can see well with the other: there may be a reason sometimes to shut one eye, but there can be none at any time for to extinguish it.
