The raising of Lazarus illustrates that Jesus is the giver of life. When Lazarus died, Jesus came to his tomb and commanded him to come back to life. And Lazarus was resurrected, showing that Jesus had the power to give life even to the dead. This miracle also demonstrated the divine nature of Jesus and strengthened the faith of his followers. While it's true that Jesus was also a friend of Mary, Martha, and Lazarus and showed emotions during this event, the main message of this miracle was to reveal Jesus' power as the giver of life.
