The other day I was having a discussion with a friend and I was told that life isn't black and white. This bothered me, I didn't push the issue, but it has given me something to think about.
I began thinking about why life couldn't be black and white. We hear that everything has its opposites, good and evil, virtue and vice, light and dark, pleasure and pain. Then I heard on the radio and advertisement for Rush Limbaugh where he made this statement, "When Good negotiates with Evil, Evil always wins!"
How could that be!?! Well, I came up with this. A statement is only true if it is 100% true. The second you add a small insignificant falsehood. The statement then becomes false. Parts of that statement may be true, but as a whole it is a lie.
In order for Good to negotiate with Evil, Good must give up on some of its "goodness" and take on some evil. Remember in the scriptures that it tells us to be white as snow, or white as wool. They use the extremely white things as examples, not white as the overcast sky.
We are the ones that came up with gray, to justify our actions. There is God and Satan, two opposites, there is no Bob in the mix. I think that there is a fine white line that we try to stay on and we keep running through it. But, because God is perfect, he can walk that line.
Here is an example, Nephi was told to kill Laban. Well, Nephi knew, "Thou shalt not kill." But, God told him, "It is better than one man die, than a nation perish in unbelief." So, there is an exception to this rule. This may be seen as a gray area, but with God's perfect judgment, he can see that white line and stay exactly on it. If he couldn't, then "God would cease to be God," because he couldn't obey the laws of God.

When I was in Physics in college. We learned that when light passes over an edge, that it is "split." That, when you look at the edge of a shadow, there is a gray area. But, when looked at closer this gray area is made up of large and small patches of light and dark. That you can look further and find that any gray seen again can be looked at again and is made up of light and dark again. So, truly there is no gray. Here is a picture where you can see the light and dark as light is passed over a razor's edge.
Gray is only seen from afar. But, under closer examination it is just a mixture of black and white.
Does this make our becoming perfect seem more difficult?
I think so!
But, what gives me comfort is the atonement. As we get tainted with spots of dark, that we can clean these and become white. Remember! "No unclean thing can enter into the kingdom of heaven."
