Uneducated Elder miraculously enabled to read, write, and preach

An unnamed man called on a mission despite having no education and being unable to read or write, feared he would fail. Following an inward prompting that the Lord would be with him, he accepted the call. Despite being past his prime, he learned to read and write and successfully baptized nineteen people.

Fuller account of this event (as retold in The Latter-day Saints' Millennial Star, Vol. 68, No. 04 (January 25, 1906), p. 63):

An Elder who was lately in the mission field relates that he had often thought while at home that he would like to perform a mission abroad; but having no education—not being able to read or write—he feared he would never have the privilege. An opportunity at last came for him to go, yet he still lacked education. While in a meeting about this time the inward promptings of the Spirit made known to him that if he would go the Lord would be with him; that he would be enabled to learn to read and write, and that should fill a useful mission. He relied upon the promise received, and went forth in obedience to the call made of him. Although past the prime of life, he readily acquired the arts of reading and writing. As a missionary he soon became very successful. By his humble efforts he was the means of bringing a number of souls to a knowledge of the truth, and within a short space of time he and his missionary companion baptized nineteen people.
