The gospel of John is different from the other three gospels. It is filled with conversations, people, and incidents in the life of Christ that do not appear in Matthew, Mark, and Luke. It is similar, however, in its overall purpose. John joined the other writers in their God-given task of documenting the greatest life this world has ever seen. As David Egner points out, John’s mission was to show us how we can come to know God through His Son, Jesus the Christ.
