Alma 33

 Alma explained - 

"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.

20 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.

21 O my brethren, if ye could be healed by merely casting about your eyes that ye might be healed, would ye not behold quickly, or would ye rather harden your hearts in unbelief, and be slothful, that ye would not cast about your eyes, that ye might perish?

22 If so, wo shall come upon you; but if not so, then cast about your eyes and begin to believe in the Son of God, that he will come to redeem his people, and that he shall suffer and die to atone for their sins; and that he shall rise again from the dead, which shall bring to pass the resurrection, that all men shall stand before him, to be judged at the last and judgment day, according to their works.

23 And now, my brethren, I desire that ye shall plant this word in your hearts, and as it beginneth to swell even so nourish it by your faith. And behold, it will become a tree, springing up in you unto everlasting life. And then may God grant unto you that your burdens may be light, through the joy of his Son. And even all this can ye do if ye will. Amen."  (Alma 33:19–23)
