To kick off our new series through 1 John, Troy reminds us that we need to love other people who follow Jesus, but we also need to know that our love for one another is our best witness to people in the world. Troy also reassures us that there was proof that Jesus really became a man, because John and others experienced Him with their senses, including their sight, hearing, and touch. In addition, John shows us that God is light, not the light, or a light, but light itself.
