I Am the Law, and the Light – 3 Nephi 15:9

9 Behold, I am the law, and the light. Look unto me, and endure to the end, and ye shall live; for unto him that endureth to the end will I give eternal life.
(3 Nephi 15:9)

It makes sense to me that the Savior is both the law and the light. We learn from the Doctrine and Covenants that commandments are actually directions or instructions for how to live successfully (D&C 82:8-9). We’re also told that, if we are obedient, we will receive “commandments not a few” (D&C 59:3-4). For people who think of commandments as a burden, that may not sound very appealing, but for those who are trying to improve each day and want all the help we can get, that sounds like a great blessing.
What does it mean to endure to the end? I think it means to stick with the program. When we sign on as disciples of the Savior, we are agreeing to a lifelong program of constant improvement. That means that He will give us assignments that are difficult, which stretch us in the ways we need to be stretched. That means that we will endure trials which are painful, from which we are expected to extract important lessons. That also means that we will receive personalized commandments which enable us to become more like our Savior and our Heavenly Father. Our part is to stay in the game, not to drop out or give up when life becomes discouraging. We need to trust our Savior as He leads us through the tutoring which we need individually in order to achieve the ultimate goal of qualifying for eternal life by His grace.
Today I will trust my Savior. I will recognize that the challenges I face and the assignments I receive from God are customized for me personally and will bless my life if I move steadily forward, exercising faith in Him.
