Text
Then the crowd responded, "We have heard from the law that the Christ will remain forever. How can you say, ‘The Son of Man must be lifted up’? Who is this Son of Man?" Jesus replied, "The light is with you for a little while longer. Walk while you have the light, so that the darkness may not overtake you. The one who walks in the darkness does not know where he is going. While you have the light, believe in the light, so that you may become sons of light." When Jesus had said these things, he went away and hid himself from them.
Although Jesus had performed so many miraculous signs before them, they still refused to believe in him, so that the word of Isaiah the prophet would be fulfilled. He said, "Lord, who has believed our message, and to whom has the arm of the Lord been revealed?" For this reason they could not believe, because again Isaiah said, "He has blinded their eyes and hardened their heart, so that they would not see with their eyes and understand with their heart, and turn to me, and I would heal them."
Isaiah said these things because he saw Christ’s glory, and spoke about him. Nevertheless, even among the rulers many believed in him, but because of the Pharisees they would not confess Jesus to be the Christ, so that they would not be put out of the synagogue. For they loved praise from men more than praise from God.
We may learn, from these verses, the duty of using present opportunities. The Lord Jesus says to us all, "Yet a little while is the light with you. Walk while you have the light, lest darkness come upon you. While you have light believe in the light." Let us not think that these things were only spoken for the sake of the Jews. They were written for us also, upon whom the ends of the world are come.
The lesson of the words is generally applicable to the whole professing Church of Christ. Its time for doing good in the world is short and limited. The throne of grace will not always be standing--it will be removed one day, and the throne of judgment will be set up in its place. The door of salvation by faith in Christ will not always be open--it will be shut one day forever, and the number of God\
