John 11: the light and the darkness

Jesus is the light that came to shine on this world. Through him, all who trust in him, have life. Jesus made a great sign to show this reality: he resurrected Lazarus. Jesus said that this sign would happen in favor of his disciples:

14-15 Then Jesus became explicit: “Lazarus died. And I am glad for your sakes that I wasn’t there. You’re about to be given new grounds for believing. Now let’s go to him.”

After the resurrection, many were led to believe in Jesus:

45 Therefore many of the Jews who came to Mary, and saw what He had done, believed in Him.

The darkness fought against the light:

47-48 The high priests and Pharisees called a meeting of the Jewish ruling body. “What do we do now?” they asked. “This man keeps on doing things, creating God-signs. If we let him go on, pretty soon everyone will be believing in him and the Romans will come and remove what little power and privilege we still have.”
53 From that day on, they plotted to kill him. So Jesus no longer went out in public among the Jews. 

It is very interesting that Jesus saw the resurrection of Lazarus, not only to ground the faith of his disciples but also to glorify him, the Son of God.

4 When Jesus got the message, he said, “This sickness is not fatal. It will become an occasion to show God’s glory by glorifying God’s Son.”
