Once again the words of Jesus bring division, even among those religious leaders who were against Him (cf. John 6:52, 7:12, 43, 9:16). The people present were beginning to realize that they could not just sit on the sidelines about Jesus and His seemingly impossible claims (John 10:17-18). Some in the audience recall the healing of the blind man, while others repeat the charges of demon possession, and accuse Him of insanity.
This is an object lesson; the mixed response to His words is exactly as Jesus said it would be. His sheep hear His voice, and they follow Him. Those who are not His sheep do not hear His voice, and they will not follow the Good Shepherd.
Some rightly reason that Jesus’ words must be judged in the light of His works. A demon possessed man would not speak and act as Jesus does. The miracle of healing the man born blind gave credibility to His words. Others dismiss Jesus and are quick to reject Him as their shepherd. Those who are opposed are intensified in their opposition. They are coming to steal, kill, and destroy (cf. John 5:18, 7:1, 19-20, 25, 8:37, 40, 10:10).
What do you believe? You can’t just set the claims of Jesus aside. He is either everything He says He is, or He is none of it. He claims exclusivity (John 14:6); He cannot be lumped in with other religions or their leaders (Acts 4:12 / 1 Timothy 2:5). He demands full allegiance. So what is it? Is He a liar, a lunatic, or Lord?
