Heber C. Kimball,
Journal of Discourses — Volume 6…
“ Brethren, I want you to understand, if you will treasure up principles of truth as you would treasure up gold and silver and precious stones—if you will treasure up truth, every truth that you treasure up, that truth is life, and that life is light. Do you not see that if you treasure up the principles of truth in you, and you have your treasury full of them, then, of course, your treasury is saviour of all? Why? Because life is light, and light is life. Do you not see, if you have got the true principles dwelling in you, if you treasure up truth, you are bound to have life ”
