Being in a rock and roll band before my mission, I've played music with a lot of different people. Trying to find the right combination of style, taste, and sound is pretty tough sometimes. Even after you find a good combination, making each person become as one, so to speak, is an extreme challenge. Often times little disagreements will come up, but there are occasions when everyone gets in the groove, and that's when music is made. The trick to getting the perfect sound is unity.
Unity is something that we need to be striving for in this life. Whether it's for a rock and roll band, a family, or just in oneself, it's an important attribute to attain. The people of Alma, after they had been baptized, we're commanded to be unified together. Mosiah 18:21 reads, "And he commanded them that there should be no contention one with another, but that they should look forward with one eye, having one faith and one baptism, having their hearts knit together in unity and in love one towards another."
Just like having unity in a rock band will produce the best music, unity in a home will produce the best people. The main person we want to be united with is our Savior, Jesus Christ. We must unite in the same cause as Him. We must develop an eye single to His glory. We must see the world as he does. We must see others as he does. It is then we will be in perfect harmony with Him and His teachings.
