READ JOHN 12:37-50
37-43) Quote from Isaiah 53:1. Isaiah 53 is a prophecy about Jesus and His death on the cross. John was reminding the readers of what had been prophesied and yet the Jews did not listen or believe; a fulfillment of prophecy. The second quote, Isaiah 6:10, is the vision Isaiah had of God on His throne. Isaiah heard the call of God, but Isaiah was to realize that the people would not listen and will refuse to see. For this cause, because they have refused to believe the Old Testament, they are also now doomed not to believe in Jesus. v. 41 gives a look into some who did believe, but kept it to themselves in fear of the rulers of their day. Why? Because they loved the approval of men rather than the approval of God.
44-50) HEAR JESUS CRY! BELIEVE IN ME! The Jews did not believe the fathers and the prophets and now they were gulty of not believing Jesus. The cause and effect here is if you reject Him, you will be judged. The very Word that they refused to believe well be there judge on the last day. Jesus spoke with authority: He was given commandment of what to speak and the commandment is eternal life, therefore He spoke just as God had commanded Him.
FATHER, MAY WE HEAR YOUR WORDS AND DRAW THEM TO OUR HEARTS IN BELIEF. HELP US TO HERE THE CRY OF JESUS TO BELIEVE UPON HIM FOR ETERMAL LIFE. AMEN.
