12:37-50 -Jesus comes to end of His public ministry
12:37-41 – Now we learn what was wrong. Although they were standing in the presence of the Light of the World, they would not open their eyes. The prophecy of Isaiah was being fulfilled. This quotes the great redemptive chapter of Isaiah 53 which speaks of the death of Christ. Christ’s death was presented to them, and they rejected Him. They were blinded to the light which was being presented to them. The most dangerous thing in the world is to hear the gospel and then turn your back on it. If you just go on listening and listening and do not accept it and act upon it, there comes the time when you cannot hear and you cannot see. God is God, and it is He who has the final word.
12:44-46 – Jesus repeats His amazing statement that He is the Light of the World. This is an extension of the time that He opened the eyes of the blind man. He will open the eyes of any who are willing to admit that they are blind and that they need the Light of the world.
12:47-50 – We are going to be judged by the Word of God. We will not be judged by our little good works. We will not be judged by what we think religion is. No, we will be judged by the Word of God. Jesus came the first time as the Savior: “I came not to judge the world, but to save the world.” The next time He will come as the Judge. The voice from heaven is still saying to us, “… This is my beloved son…hear ye him” (Matt. 17:5).
Men had turned their backs on that voice; they had rejected the King. When they had done this, the King rejected them. He is always the King!
