In Jesus' final sign, recorded in John 11:1-54, he raised his friend Lazarus from the dead. As a sign, it was not to be a regular occurrence but an extraordinary event that pointed to Jesus as the only source of life from the dead and of eternal life. In the face of death, Jesus expressed anger and sadness even as he exercised dominance. Jesus' mastery over death should interest all who lose loved ones or who will themselves eventually die. (sermon notes)

As Paul demonstrated in his trial before Governor Felix, Christians must testify about Christ with our words and with our lives.
