The Plain Gospel
In 3 Nephi 27:13-17, Jesus summarizes the Gospel. Christ came into the world to do His father's will. He suffered and died for men. We then have a choice to accept Jesus or reject Him. Those who accept Him and endure to the end are saved, while those who reject Him will not be saved.
Marvin J. Ashton said, "The truths of the gospel of Jesus Christ are plain, precious, and powerful. The lives of the worthy are plain, precious, and powerful." (Marvin J. Ashton, “The Power of Plainness,” Ensign, May 1977, 66)
No Unclean Thing
3 Nephi 27:19 is a very important verse to remember and to read often. “No unclean thing can enter into his (God’s) kingdom…” If we expect to live eternally with God, then we must act as he does and keep his commandments and repent.
Judged By the Scriptures
How will we know what we’ll be judged on? We read the scriptures. For out of the scriptures we find what we’ll be judged by. This life is an open book test. We have the requirements right before us and if we but read what they are and then apply them to our lives, then we’ll be saved (see 3 Nephi 27:25-26).
The Straight and Narrow
Being elite on this earth doesn’t amount to much. The only elite group that really counts is the final one that finds its way to the gate at the end of the straight and narrow path. All other "races" are nothing compared to this one. The only judge that matters is God (see 3 Nephi 27:33).
Wo unto them
3 Nephi 28:34-35 – We read of a great condemnation in these verses. If we do not receive (obey) Jesus or his servants, then it will have been better that we were never born! We will not be able to avoid the justice of an offended God.
Where much is given, much is required. (D&C 82:3)
Translated Beings (Transfigured)
A translated being is a person who is changed so that he does not experience pain or death or even temptation until his resurrection to immortality (see "Guide to the Scriptures" Translated Beings).
3 Nephi 28:39 states, "there was a change wrought upon them, insomuch that Satan could have no power over them … the powers of the earth could not hold them." They were beyond this world, yet in it.
