My attention was drawn recently to the preface to the sermons by John Wesley
TO candid, reasonable men, I am not afraid to lay open what have been the inmost thoughts of my heart. I have thought, I am a creature of a day, passing through life as an arrow through the air. I am a spirit come from God, and returning to God: just hovering over the great gulf; till, a few moments hence, I am no more seen; I drop into an unchangeable eternity! I want to know one thing,—the way to heaven; how to land safe on that happy shore. God himself has condescended to teach me the way. For this very end He came from heaven. He hath written it down in a book. O give me that book! At any price, give me the book of God! I have it: here is knowledge enough for me. Let me be homo unius libri.* Here then I am, far from the busy ways of men. I sit down alone; only God is here. In His presence I open, I read His book; for this end, to find the way to heaven. Is there a doubt concerning the meaning of what I read? Does anything appear dark or intricate? I lift up my heart to the Father of Lights:—“Lord, is it not Thy word, ‘if any man lack wisdom, let him ask of God?’ Thou givest liberally, and upbraidest not. Thou hast said, ‘if any be willing to do Thy will, he shall know.’ I am willing to do, let me know Thy will.” I then search after and consider parallel passages of Scripture, “comparing spiritual things with spiritual.” I meditate thereon with all the attention and earnestness of which my mind is capable. If any doubt still remains, I consult those who are experienced in the things of God: and then the writings whereby, being dead, they yet speak. And what I thus learn, that I teach.
