The Spirit of God in man’s heart is not deceitful. It is too holy to deceive, and too wise to be deceived in this point of assurance. We plough with the Spirit’s heifer, or else we could not find out this riddle: Where there is an object to be seen, and an eye to see, and light to discover the object to the eye, sight must needs follow. In a true believer, after he is enlightened, as there is grace to be seen, and an eye of faith to see, so there is a light of the Spirit discovering that grace to that inward sight. In the bottom of a clear river, a clear eyesight may see anything. Where nothing is, nothing can be seen.
