In the Joseph Smith Translation of the Bible, we read that “the Lord hath visited” Joseph, the son of Jacob spoken of in the Old Testament, and that Joseph was given great promises concerning his posterity (JST, Genesis 50:24). As Lehi testified, “Joseph truly saw our day” (2 Nephi 3:5), meaning the day of Lehi and his posterity, and knew that in the future God would raise up “a choice seer” (verse 7), namely the great prophet who was his namesake (see verse 15). Joseph knew also that it would be primarily his descendants whom the Lord would call upon first in these last days to carry the gospel to additional lost members of the house of Israel scattered among the nations of the earth, in compliance with the covenant God made with Abraham (see Bible Dictionary, “Joseph,” 716–17; Guide to the Scriptures, “Joseph, Son of Jacob”). Obviously, since the Lord kept His covenant with Joseph, He will also keep His covenants with us if we are righteous as well.
Lehi’s teaching is a great example of how Heavenly Father honored the covenant He made with Joseph. We can have the confidence that God will always honor His covenants.
