Nephi is moved by the spirit of prophecy to bear witness to the truthfulness of the gospel before his people. He pours out his soul in the expression of joy over the things that delight him most—the words and testimony of the prophets—Isaiah and Jacob, in this case—which prove that all of the words of God are true. Nephi finds spiritual fulfillment in the opportunity to confirm the divinity of Christ’s mission and the power of the Atonement, based on grace, justice, mercy, and love. In all of this, Nephi chooses to blend his witness with that of his brother Jacob and, especially, with the prophet Isaiah, declaring that “by the words of three, God hath said, I will establish my word. Nevertheless, God sendeth more witnesses, and he proveth all his words” (verse 3).
