Introduction of John
The Gospel of John, traditionally attributed to the apostle John and written in the 80s–90s AD, stands apart with its deeply theological and reflective tone. Focused on Jesus’ identity as the eternal Word made flesh, it records selected signs and profound “I Am” statements. Key figures include the beloved disciple, Mary Magdalene, and doubting Thomas. Rather than repeating the other Gospels, John invites readers into an intimate encounter with Jesus as the source of life and light. Its purpose is clear: that readers might believe and have life in His name.
