Jesus
Jesus — Greek form of Joshua/Yeshua, "Jehovah saves"
And I know that the Lord God will consecrate my prayers for the gain of my people. And the words which I have written in weakness will be made strong unto them; for it persuadeth them to do good; it maketh known unto them of their fathers; and it speaketh of Jesus, and persuadeth them to believe in him, and to endure to the end, which is life eternal. 2 Nephi 33:4
Nephi sums up why his record matters: it talks about Jesus and persuades people to believe in Him and endure to the end. His whole book is a witness of Christ.
How we know: the verse itself names Him · the chapter heading names Him
- alludes to 2 Nephi 25:26 — Nephi's earlier statement of purpose: "we talk of Christ ... that our children may know to what source they may look."
- alludes to 2 Nephi 31:20 — Same doctrine of Christ: press forward with steadfastness in Christ and endure to the end to receive eternal life.
