For it must needs be, that there is an opposition in all things. 2 Nephi 1:81
When I consider the beautiful things of creation I marvel at God’s wisdom and mercy. He could have made the earth all one color or no color at all. Things could be quite dull and uninteresting and simply perform their function with no form that catches the eye or brings pleasure to the other senses.
But not only is there variation in all created things, there is contrast. Lehi preached that there was in creation an opposition in all things. The beautiful and the unattractive, the sweet and the bitter, the strong and the weak were all given to us that we might recognize the distinction between good and evil. He then gave purpose to life by giving us the freedom to choose liberty and eternal life or to choose captivity and death.
