It is striking how man cannot stop trying to create more light, always improving light in houses, buildings, stadiums and other outdoor places covered in the darkness of night. Man cannot seem to lose his fascination with light. We are always creating light that casts farther and is more penetrating and pleasing by degrees. In 1 John 1:5-7, John brings us into the world of light and darkness. He makes it very plain that to walk in darkness is to be deprived of everything beautiful and good. When you walk in darkness, it is a darkness that can be felt. You are separated from the light, and life and love of God. And, you cannot have the fullness of loving fellowship with God and with His people in your journey through this world. But, what does it mean to walk in the light and in darkness? John answers this question.
