“Inasmuch as Ye Shall Keep My Commandments, Ye Shall Prosper”
1 Nephi 2:20
20 And inasmuch as ye shall keep my commandments, ye shall prosper, and shall be led to a land of promise; yea, even a land which I have prepared for you; yea, a land which is choice above all other lands.
Elder Bruce R. McConkie wrote:
“Obedience is the first law of heaven. All progression, all perfection, all salvation, all godliness, all that is right and just and true, all good things come to those who live the laws of Him who is Eternal. There is nothing in all eternity more important than to keep the commandments of God.”
