William Jay again

It is in religion as it is in nature, the understanding sways the will and affections. "Wisdom is the principle thing;" therefore we are to "get wisdom, and with all our getting to get understanding." The Apostle prays for the Ephesians, "That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of Him: the eyes of your understanding being enlightened; that ye may know what is the hope of His calling." Till we see the evil of sin, we shall never abhor it, and mourn over it. Till we know Christ, we cannot desire Him, depend upon Him, apply to Him, rejoice in Him. Till we know Him, we can know nothing, feel nothing, possess nothing, enjoy nothing.
