There is no better scripture than this one which demonstrates the divine necessity for opposition in all things. Without the building of opposition into God's creations there would be no existence. This is amazing! But in fact, it is only as we become aware of the combination of opposition in all things that we are able to comprehend their true reality. How could we say something is hot if there was no cold? How could we say something is good if there was no evil? Everything exists in relation to its opposite and Lehi is saying that without its opposition nothing exists. Even the elements are a combination of the positive and negative electrons.
