"Day after day, and especially on Saturdays and Sundays when there were no organizations [sessions] in the temple, I went there when I could be alone. I was very humble . . . I was searching for this . . . I wanted to be sure. . . . We had this special prayer circle, then I knew that the time had come. I had a great deal to fight, of course, myself largely, because I had grown up with this thought that Negroes should not have the priesthood and I was prepared to go all the rest of my life till my death and fight for it and defend it as it was. But this revelation and assurance came to me so clearly that there was no question about it." 

Spencer W. Kimball
