Vision of an Angel to a young man in Wales

A young man who was conflicted between joining the Baptists (his parents' religion) or the Church of Jesus Christ of Latter-day Saints prayed for guidance. Following his prayer, an angel with a flaming sword appeared by his bedside and told him, 'Woe be unto you if you do not unite with the Church of Jesus Christ of Latter-day Saints.' The experience was repeated, and though he cried out, his parents in the next room could not hear the voice or see the vision.

Fuller account of this event (the complete account as preserved in The Latter-day Saints' Millennial Star, Vol. 29, No. 36, 7 September 1867, p. 574):

A young man in Wales, who was much concerned about his soul's salvation, and who was undecided whether to join the Baptists, to which sect his parents belonged, or the Church of Jesus Christ of Latter-day Saints, prayed earnestly to the Lord for direction. While thus engaged, an angel with a flaming sword appeared by his bedside, and said, 'Woe be unto you if you do not unite with the Church of Jesus Christ of Latter-day Saints.' The vision was repeated, and although he cried out, his parents, who were in the next room, could not hear the voice nor see the vision.
