We are strongly commanded in the scriptures to search and study Isaiah.
"And now, behold, I say unto you, that ye ought to search these things. Yea, a commandment I give unto you that ye search these things diligently; for great are the words of Isaiah." 3 Nephi 23:1
"Wherefore, I write unto my people, unto all those that shall receive hereafter these things which I write, that they may know the judgments of God, that they come upon all nations, according to the word which he hath spoken." 2 Nephi 25:3
But many find Isaiah quite challenging.:
"...For behold, Isaiah spake many things which were hard for many of my people to understand; for they know not concerning the manner of prophesying among the Jews." 2 Nephi 25:1
"Wherefore, hearken, O my people, which are of the house of Israel, and give ear unto my words; for because the words of Isaiah are not plain unto you, nevertheless they are plain unto all those that are filled with the spirit of prophecy." 2 Nephi 25:4
