2 Nephi 28 exposes the “false and vain and foolish doctrines” of the devil (v.9). Pride seems to be the main reason for people embracing Satan’s system of justification (vv. 12,13,14,15). Unlike Nephi, whose main concern is to teach with such “plainness” that “no man can err” (2 Ne 25:7,20,28), Satan prefers the “precepts of men” which lead people to “err” (2 Ne 28:14). His tactics are also exposed in 2 Nephi 9:20-22. Perhaps some of these have even worked on you or me. Nephi is quick to warn us of accepting such tempting SIN-speration. Just take a look at the number of “wo’s” that are found in vv. 15-32. One way to define wo is “grief, sorrow, misery”. Not a very tempting doctrine in the end.
However Satan is very persuasive, and if he can’t get you to accept his doctrine, perhaps he can get you to reject God’s doctrine. This seems to be the message of 2 Nephi 29. Instead of embracing the Book of Mormon as Another Testament of Jesus Christ, Satan is able to convince people that “there cannot be any more Bible”, nor is there need for more of God’s word (v. 3). In this chapter it is actually the Lord explaining to us that there is absolutely no way that this should be a reasonable thought (2 Nephi 28:30 is the transition from Nephi writing to the Lord speaking. Chapter 29 begins with the word “But”, and is a continuation of the Lord speaking.) The Lord runs through a series of questions to help us understand this (vv. 4-8). He then goes on to explain that there are other books that have been written by the lost tribes of Israel that will also be added to the records of the Jews and the Nephites (vv. 9-14. See also an object lesson about the gathering of Israel that uses the Bible and The Book of Mormon as an illustration in, Ezekiel 37:15-20). I think that God gets His point across quite well.
Elder L. Tom Perry, of the Quorum of the Twelve Apostles, put it this way: “Neither the Bible nor the Book of Mormon in and of themselves is sufficient. Both are necessary for us to teach and learn about the full and complete doctrine of Christ. The need for the other does not diminish either one of them. Both the Bible and the Book of Mormon are necessary for our salvation and exaltation. As President Ezra Taft Benson so powerfully taught, ‘When used together, the Bible and the Book of Mormon confound false doctrines’ (“A New Witness for Christ,” Ensign, Nov. 1984, 8).” (“The Power of Deliverance“, Ensign, May 2012) See my post on #BOMTC Day 5 for more on this.
In 2 Nephi 30 Nephi is speaking again and he will use the next two chapters to explain to us THE DOCTRINE OF CHRIST (2 Nephi 31:2,21). Chapter 30 is Nephi’s argument for the Book of Mormon and its power to help gather both the Gentiles and the House of Israel. Chapter 31 is an illustration of “the doctrine of Christ” (vv. 2,21), using Jesus as the example. However, it is not all Nephi. Both the Father and the Son are quoted in this chapter (vv. 11,12,15,20) and explain “the doctrine of Christ”. I will leave it to you to discover this doctrine and contrast it with the doctrine proposed by Satan in 2 Nephi 28. A good talk to go along with these chapters was given by Elder D. Todd Christofferson, “The Doctrine of Christ”, during the April 2012 Annual General Conference.
