Verse 10 tells us that in this way all men may come unto God and stand in the presence of him to be judged. Judgment is another word of temple significance bringing the idea of opposition as we see in the creation account with the light being separated from the dark, the wet from the dry, the mountains from the valleys, the animals from the plants, male and female. We learn in the temple that opposition is the fundamental characteristic of the world in which we find ourselves and when we understand that, then lots of things like obedience and disobedience, choosing Christ or choosing Satan, life or death become fundamental choices explaining the reasons why we are here.
How are things opposed to each other, but also as Lehi says a compound in one? God created something which in the beginning was pure and unified and good, but then in the world where you have opposites, we must learn to choose one or the other. Lehi understands that there is a choice between good and bad, between happiness and misery and yet this will not necessarily deteriorate into chaos. It’s controlled because each thing has something that is set in opposition to it.
Everything that comes from God is good. Light, life, truth, joy and good. Satan takes away light; darkness is the absence of light. Satan takes away life; death is the absence of life. Satan takes away truth; falsehood is the absence of truth. Satan takes away joy; misery is the absence of joy. And Satan takes away good; evil is the absence of good. It is the existence of opposites coupled with our agency that gives meaning and purpose to our mortal probation.
