One night in Kenya, my wife and I were in the bedroom kindly given to us, and I was attempting to read. My sight isn’t very good to begin with, but I was having trouble reading because of the dim light. I gave up and that sparked a conversation about how there was a dark lightness in the kitchen.
Many homes in Kenya are not built to Western standards. In fact, the home we stayed in has only 2 single-plug electrical outlets! Electricity is a convenience rather than a necessity so whole rooms are lit by a single bulb hanging from a dangling wire in the ceiling.
We agreed between ourselves that the next time in town we would buy new bulbs for the whole house, the brightest bulbs possible.
Soon came the evening when I replaced all the bulbs in the house. Everyone rejoiced as the dark lightness that existed moments before was exchanged for brightness. Now we could take photos without the flash on our phones going off, and I could read in bed.
Spiritually speaking, unsaved people think they see the meaning and purpose of life. They are convinced that they comprehend truth about the universe, themselves, and God. Jesus said otherwise. The lamp of the body is the eye. If therefore your eye is good, your whole body will be full of light. But if your eye is bad, your whole body will be full of darkness. If therefore the light that is in you is darkness, how great is that darkness! (Matthew 6:22-23).
Jesus is the Light (John 9:5). Apart from Him dwelling within a person, that person is viewing everything from utter and complete darkness and doesn’t even know it.
I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life (John 8:12).
