“As it is with spiritual discoveries and affections given at first conversion, so it is in all subsequent illuminations and affections of that kind; they are all transforming. There is a like divine power and energy in them as in the first discoveries; they still reach the bottom of the heart, and affect and alter the very nature of the soul, in proportion to the degree in which they are given. And a transformation of nature is continued and carried on by them to the end of life, until it is brought to perfection in glory.”
