[18] All profound spiritual teachers contrast _wisdom_ and _knowledge_--what is here called "knowledge in the Spirit" and "knowledge in the flesh," or, what is perhaps more frequently called "knowledge of the heart" and "knowledge of the head." The latter expression means a knowledge of fact--the knowing that a thing is so by evidence which satisfies the mind. The former expression means the soul's immediate grasp of truth by the test of practical experience. The goal in one case is the establishment of some fact; the goal in the other case is the production of positive life and character by the appreciation of the truth. While there is this knowledge in the flesh, deceit and self will conform to anything, and will say Yes, Yes, to that it doth not know. The knowledge which the world hath of what the prophets and apostles spake, is a fleshly knowledge; and the apostates from the life in which the prophets and apostles were have got their words, the Holy Scriptures, in a form, but not in the life nor spirit that gave them forth. So they all lie in confusion; and are making provision for the flesh, to fulfil the lusts thereof, but not to fulfil the law and command of Christ in His power and Spirit. For that they say they cannot do; but to fulfil the lusts of the flesh, that they can do with delight. Now, after I had received that opening from the Lord, that to be bred at Oxford or Cambridge was not sufficient to fit a man to be a minister of Christ, I regarded the priests less, and looked more after the Dissenting people.[K] Among them I saw there was some tenderness; and many of them came afterwards to be convinced, for they had some openings. [K] The "Separatists"--especially here the Congregationalists and Baptists. But as I had forsaken the priests, so I left the separate preachers also, and those esteemed the most experienced people; for I saw there was none among them all that could speak to my condition. When all my hopes in them and in all men were gone, so that I had nothing outwardly to help me, nor could I tell what to do, then, oh, then, I heard a voice which said, "There is one, even Christ Jesus, that can speak to thy condition";[19] and when I heard it, my heart did leap for joy. [19] Compare this great passage where George Fox describes his conversion with Paul's account of the spiritual _fiat lux_ in 2 Cor. 4: 6, "For God who commanded the light to shine out of darkness [the first _fiat lux_] _hath shined in our hearts_ to give the light of the knowledge of the glory of God in the face of Jesus Christ."
