"Isaiah 12 tells of a millennial day when men shall 'draw water out of the wells of salvation'; and Zechariah, speaking of that same day of peace and righteousness, tells how 'living waters shall go out from Jerusalem' (Zech. 14:8.)
"From all this it is perfectly clear that men must drink living water to be saved. As Moroni expressed it: 'Come unto the fountain of all righteousness and be saved.' (Ether 8:26.) And the same truths flow from the same fountain yesterday, today, and forever." (The Promised Messiah, p. 206)
