The phone rang in the middle of the night. As I scrambled across the room in total darkness, I staggered and bumped into things. This little experience reinforced the truth that without spiritual light I will also stumble, fall and fail. Jesus Christ promised, “I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life” (John 8:12). The Savior’s light is power. But I must follow Him to activate it. “The answer to our weakness is to plug into the inexhaustible power of the Lord. That plugging in process involves commitment. Once we truly commit to the Lord to do his will at all costs, we throw the switches that send his power surging to us” (Duane Hiatt). I can personally witness that committing to follow Christ and obeying His commandments enable me to do what I could not do alone. I am empowered beyond my natural ability to work, learn, serve, and find joy in life. Each week as I partake of the emblems of the sacrament, I eagerly renew my covenant to stay on the illuminated path of the Savior Jesus Christ.
