The absence of light causes darkness.
When the darkness of night falls, we do not despair and worry that the sun is extinguished. We do not postulate that the sun is not there or is dead. We understand that we are in a shadow, that the earth will continue to rotate, and that eventually the rays of the sun will reach us once again.
Darkness is not an indication that there is no light. Most often, it simply means we’re not in the right place to receive the light.
Spiritual light continually shines upon all of God’s creation.
It is up to us to be in the right place to see the divine light and truth of the gospel of Jesus Christ. Even when night has fallen and the world seems dark, we can choose to walk in Christ’s light, keep His commandments, and courageously testify of His reality and His greatness." (Dieter F. Uchtdorf)
