We must depend upon the Spirit in our preparations. Is this the fact with us all? Are you in the habit of working your way into the meaning of texts by the guidance of the Holy Spirit? Every man that goes to the land of heavenly knowledge must work his passage thither; but he must work out his passage in the strength of the Holy Spirit, or he will arrive at some island in the sea of fancy, and never set his foot upon the sacred shores of the truth. You do not know the truth, my brother, because you have read "Hodge's Outlines", or "Fuller's Gospel worthy of all Acceptation"; or "Owen on the Spirit", or any other classic of our faith. You do not know the truth, my brother, merely because you accept the Westminster Assembly's Confession, and have studied it perfectly. No, we know nothing till, we are taught, of the Holy Ghost, who speaks to the heart rather than to the ear.
