John 12:36
Believe in the light while you have it, so that you may become children of light.' When he had finished speaking, Jesus left and hid himself from them — the command to believe in the light is the final call to discipleship and faith; belief in Jesus makes one a child of light, transferred from darkness to light. Jesus' subsequent withdrawal and hiding from the crowd marks the end of public ministry; the time for public revelation is ending as the passion approaches.
