Forward with faith - 1 Nephi 3,4
Nephi and his brothers kept turning back and trying different ways to get the brass plates from Laban and fulfill the commandment they had been given. Laman and Lemuel eventually decided it was too hard and decided to beat Nephi and Samuel, luckily an angel stopped them. And afterward Nephi was undeterred by his brother's continued resistance. He kept moving forward, even though he was not certain that he knew what he was going to do he was "led by the spirit not knowing beforehand the things which [he] should do". I love that scripture.
Have you stressed out because of a grim or uncertain looking future? Have you ever been faced with a challenge in your relationship with your spouse? Have your kids ever become such a challenge that you are at a loss as of what to do? Well, Nephi didn't know what to do, but he had faith that God was more powerful than armies and would show him what to do because he was commanded to.
Uncertainity is simply an opportunity to show faith, an opportunity to rely on God for guidance and help. I know it is hard to remember to have faith in the moment, and many times a step back, a deep breath, and a prayer are needed, but if you are led by the spirit you will make the right decision.
