We get to know people by spending time with them. We observe their actions, listen to their words, and notice how they treat others. Over time, we learn who they really are. John spent about three years with Jesus, and by writing this detailed account of Jesus’s life, John gave us the opportunity to decide for ourselves who Jesus was, and is, and what difference He makes to our lives. John had made up his mind. He believed that Jesus was the Creator, the Son of God, and God in flesh sent to redeem the world (see 1:3, 14; 3:16). Knowing Jesus had transformed John’s life. And John’s Gospel calls us to the same transformation. It allows us to see what John saw, feel what he felt, and believe what he believed.
