Alma Instructs the People to Believe in the Son of God
Alma 33:19–22
19 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.
The Prophet Joseph Smith said:
“The fundamental principles of our religion are the testimony of the Apostles and Prophets, concerning Jesus Christ, that He died, was buried, and rose again the third day, and ascended into heaven; and all other things which pertain to our religion are only appendages to it.”
(Teachings of Presidents of the Church: Joseph Smith [2007], 49.)
