Doctrine and Covenants 122:7

7 And if thou shouldst be cast into the apit, or into the hands of murderers, and the sentence of death passed upon thee; if thou be cast into the bdeep; if the billowing surge conspire against thee; if fierce winds become thine enemy; if the heavens gather blackness, and all the elements combine to chedge up the way; and above all, if the very jaws of dhell shall gape open the mouth wide after thee, know thou, my son, that all these things shall give thee eexperience, and shall be for thy good.
