John recounts two events in Jesus' life that highlight who he is. In the first event, Jesus interacts with a lame man calling him to believe and then healing him. The second event involves Jesus' public dialogue with the religious leaders about his interaction with the lame man who he healed on the Sabbath. These two events reveal who God really is through the person of Jesus. He is personal and relational. He is with people and has the power to deliver from sin and suffering. To have this in life only requires belief in Jesus and his work on the cross to pay for sin.
