Nephi is the only one who will call Jesus the "Son of the Most High God", the "Son of the Everlasting Father", or the "Son of Righteousness." He will call him "the Christ", "the Beloved Son", and the "Very God of Israel." What stands out is how many times Nephi refers to Jesus specifically as a very devoted, beloved son.
If Nephi came and introduced himself to us, and we asked him, "So, Nephi, tell us a little bit about yourself," he would begin by saying, "I Nephi, having been born of goodly parents," Nephi’s identity as the loyal son, as the one who would always do the will of his father, Lehi, and the will of God was a very important part of his personality and character. Unlike Laman, Lemuel, and others, Nephi was the quintessential, obedient son. It is not at all surprising that he would see Jesus’ submission to the will of His Father in much the same way.
