His itinerant life commenced in 1809, under the elder Dr. Chandler, and continued till 1848, nearly forty years.

He was stationed for twelve years at different times in Philadelphia, and held other important charges. His early education was limited, but constant reading and close application, added to great natural, abilities, made him an able minister of the New Testament. He was known by the title of Old Father Miller" far and wide, and he was loved and honored by all who knew him, both in and out of the Church. He was a good friend to the young, and took great interest in the Sabbath-school. He took many a young man by the hand, and helped him into the ministry. He died in 1848.
