Read John 19.
Pontius Pilate was a Roman. He was assigned a powerful position in the Roman Empire over the area of Judea so he had to keep tabs on potential threats and problems in his region. But there was really no reason for him to fear anyone in Israel. With Roman soldiers at his disposal, any uprising by the Jewish people could be easily squelched. Any political would-be leaders could be dispensed with easily.
It is surprising, then, to read in verse 8 that “Pilate… was even more afraid” when he heard that Jesus claimed to be the Son of God. I would expect a man as Roman and as powerful as he was to laugh at such a claim.
Pilate, however, did not laugh.
He seems to have taken the charge very seriously. In verse 9b he asked Jesus where he was from and in verse 10 he scolded Jesus for not answering him. When Jesus finally did answer Pilate, stating that all the power he had was allowed him by God (v. 11), Pilate did not react as one who was insulted. Instead, “From then on, Pilate tried to set Jesus free” (v. 12). It took some political bullying by the Jewish leaders (v. 12bff) to get Pilate to send Jesus off for crucifixion (vv. 13ff).
What caused Pilate to be so fearful of Jesus? Remember that anything Jesus said was God’s word by definition. Since it was God’s word, it had the power of God behind it. That power, plus the witness of the Spirit, gave Jesus’ words self-authenticating power. Pilate knew that he was hearing the word of God and, on some level, knew that Jesus was the Son of God.
Do you understand the self-authenticating power of God’s word? Unbelievers like Pilate may resist God’s word and evade accountability to it. But, because it is God’s word, they feel the conviction of sin within when they heard God’s word. They know through the convicting work of the Spirit that Jesus is truly God.
