Lehi testifies to his sons that God is eternally consistent and how they will fare (physically and spiritually) depends on their choices in relation to God’s standards:
“His ways are righteous forever. And he has said that: Inasmuch as ye shall keep my commandments ye shall prosper in the land; but inasmuch as ye will not keep my commandments ye shall be cut off from my presence.” (2 Nephi 1:20)
-What does it mean to prosper in the land? And, how is it the opposite of being cut off from God?
Teachings of Latter-day Prophets, Seers, and Revelators:
“When I say prosperity I am not thinking of it in terms of dollars and cents alone. … But what I count as real prosperity, as the one thing of all others that is of great value to every man and woman living, is the growth in a knowledge of God, and in a testimony, and in the power to live the gospel and to inspire our families to do the same. That is prosperity of the truest kind” (Heber J. Grant, Teachings of Presidents of the Church: Heber J. Grant , 124).
