Light attracts, it gives life, and it brightens. That's what the message of resurrected Jesus does for all who receive him. But not all will, for light also repels. Some in Jesus' own day were on an endless pursuit of signs to validate his claims. Even the resurrection would not do. He knew as much, which is why in Luke 11:29–36, Jesus responded to their demand tersely, "No sign will be given to [them] except the sign of Jonah," that is, the sign of life from the dead. What we do with the risen Christ decides what's inside us, whether darkness or light.
