Like Frederick G. Williams, I am commanded to strengthen and lift the weak and depressed. By simply being happy and letting my light shine, I can lift others. This will also promote the Glory of God! Will I "stumble and fall when the storms descend, and the winds blow, and the rains descend, and beat upon [my] house"? Or will I be strong and be a light, no matter how dark my surroundings are?
It is important for me to study and learn! I need to become acquainted with all good books, people, etc. I feel like this is exactly what I am trying to do with my education at BYU; it is very important that I be aware of all different kinds of people and places in the world so that I can understand and lift others. As I understand them I will be more able to serve them.
In closing I'd just like to share how much I loved vs. 12 of section 100: "continue your journey and let your hearts rejoice; for behold, and lo, I am with you even unto the end." I think this is such a comforting scripture, especially to place at the end of these instructions for the first presidency. The Lord will not leave us, so we must continue in joy, even unto the end!
