The greatest teachers are those who take deep, hard to understand truths and put them in simple, understandable language and examples we can understand. This is a gift God gave to the Apostle John. He uses the contrast of walking in the light and walking in the darkness, two concepts that are easy to understand, especially at this time of year. The example is easy to understand, but the truth behind it is going to challenge us and confront some truths and mistruths in our own lives.
