I believe its true! Given the writings of 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). This was given by the Savior to the Nephites, but the commandment to “search these things diligently” forms a challenge that continues for us today. Isaiah had a wide perspective of God’s workings with His children. He understood the power and principles of the Zion society and saw their application for his day and for the future. While strengthening the spiritual of his own day, he prophesied of the establishment of Zion for those who would be called to carry it out. The first part of his writings contains many references to this great event.
