Behold, he was spoken of by Moses; yea, and behold a type was raised up in the wilderness, that whosoever would look upon it might live. And many did look and live. But few understood the meaning of those things, and this because of the hardness of their hearts. But there were many who were so hardened that they would not look, therefore they perished. Now the reason they would not look is because they did not believe that it would heal them (Alma 33:19-20).
