After Lazarus has died, there is this exchange in John 11 between Jesus and Martha (John 11:21-27).
21 Martha said to Jesus, “Lord, if You had been here, my brother would not have died. 22 But even now I know that God will give You whatever You ask of Him.” 23 “Your brother will rise again,” Jesus told her. 24 Martha replied, “I know that he will rise again in the resurrection at the last day.” 25 Jesus said to her, “I am the resurrection and the life. Whoever believes in Me will live, even though he dies. 26 And everyone who lives and believes in Me will never die. Do you believe this?” 27 “Yes, Lord,” she answered, “I believe that You are the Christ, the Son of God, who was to come into the world.”
What does this tell us about expectations about the Messiah? Why is Jesus saying "I am the resurrection and the life" and "Whoever believes in me will live, even though he dies" received with "Yes, you're the Christ, the Son of God"?
