“These things are written that you might believe that Jesus is the Christ” (John 20:31). This is how John concludes his own biography of Jesus. He wanted the young, the old, the sick, the well, the despairing, the hopeful, the skeptics, the faithful, and whoever reads his account of Jesus to believe and trust Him more fully. But what did John want them to believe? He wanted them to believe that Jesus alone brought eternal life into the present, broken world. And for all who enter this eternal life with God right now, we—like John—are exiles. For all who enter a relationship with Jesus, we will very likely be marginalized and dismissed because we follow Him. So, what does it mean to believe? And how do we mature in believing? What does it mean to remain faithful to God when the pressure is on? These are the things that John will help us explore by showing us the glory and beauty of Jesus.
