When about fourteen years of age I began to reflect upon the importance of being prepared for a future state, and upon enquiring the plan of salvation I found that there was a great clash in religious sentiment; if I went to one society they referred me to one plan, and another to another; each one pointing to his own particular creed as the summum bonum of perfection: considering that all could not be right, and that God could not be the author of so much confusion I determined to investigate the subject more fully, believing that if God had a church it would not be split up into factions, and that if he taught one society to worship one way, and administer in one set of ordinances, he would not teach another principles which were diametrically opposed. Believing the word of God I had confidence in the declaration of James [1.5]… I retired to a secret place in a grove and began to call upon the Lord, while fervently engaged in supplication my mind was taken away from the objects with which I was surrounded, and I was enwrapped in a heavenly vision and saw two glorious personages who exactly resembled each other in features, and likeness, surrounded with a brilliant light which eclipsed the sun at noon-day. They told me that all religious denominations were believing in incorrect doctrines, and that none of them was acknowledged of God as his church and kingdom. And I was expressly commanded to "go not after them," at the same time receiving a promise that the fulness of the gospel should at some future time be made known unto me.
