Quote by Joseph Smith as quoted by Martha Jane Knowlton Coray
Knowledge is necessary to life and godliness. Woe unto you priests and divines who preach that knowledge is not necessary unto life and salvation. Take away Apostles, etc., take away knowledge, and you will find yourselves worthy of the damnation of hell. Knowledge is revelation. Hear, all ye brethren, this grand key: knowledge is the power of God unto salvation.
Quoted by Martha Jane Knowlton Coray, reporting a discourse given by Joseph Smith on May 21, 1843, in Nauvoo, Illinois; Martha Jane Knowlton Coray, Notebook, Church Archives.
