Please see the information below from Jehovah's Witnesses. Jesus was referring to Jehovah as being the Most High over the earth and allowing men to experiment with self rule. Notice, he also allowed Satan certain authority or power over Job and Satan himself offered Jesus all the Kingdoms at Matthew 4 so this is not to say that these men are being guided by God, but instead have been allowed to experiment with human rule, but soon God will crush them establishing his own government or kingdom (Daniel 2:44).
The one who handed him over was Judas, and he clearly knew what he was doing knowing Jesus was the Son of God and the Messiah. He also knew what was prophesied and Jesus himself mentioned someone would betray him. This advanced knowledge made it unforgivable for what he did. Pontious may have not known exactly who Jesus was, thus still had an opportunity for forgiveness.
(Luke 22:53) While I was with YOU in the temple day after day YOU did not stretch out YOUR hands against me. But this is YOUR hour and the authority of darkness.”
(John 7:30) Hence they began seeking to get hold of him, but no one laid a hand upon him, because his hour had not yet come.
(John 10:18) No man has taken it away from me, but I surrender it of my own initiative. I have authority to surrender it, and I have authority to receive it again. The commandment on this I received from my Father.”
(Romans 13:2) Therefore he who opposes the authority has taken a stand against the arrangement of God; those who have taken a stand against it will receive judgment to themselves.
(Revelation 13:7) And there was granted it to wage war with the holy ones and conquer them, and authority was given it over every tribe and people and tongue and nation.
What is unforgivable sin?
Knowledge brings greater responsibility. Pilate’s sin was not as great as that of the Jewish religious leaders who turned Jesus over to the governor, nor that of Judas, who betrayed his Lord. (Joh 19:11; 17:12) Jesus told Pharisees of his day that if they were blind, they would have no sin, evidently meaning that their sins could be forgiven by God on the basis of their ignorance; however, because they denied being in ignorance, ‘their sin remained.’ (Joh 9:39-41) Jesus said they had “no excuse for their sin” because they were witnesses of the powerful words and works proceeding from him as the result of God’s spirit on him. (Joh 15:22-24; Lu 4:18) Those who, either in word or by their course of action, willfully and knowingly blasphemed God’s spirit thus manifested would be “guilty of everlasting sin,” with no forgiveness possible. (Mt 12:31, 32; Mr 3:28-30; compare Joh 15:26; 16:7, 8.) This could be the case with some who came to be Christians and then deliberately turned from God’s pure worship. Hebrews 10:26, 27 states that “if we practice sin willfully after having received the accurate knowledge of the truth, there is no longer any sacrifice for sins left, but there is a certain fearful expectation of judgment and there is a fiery jealousy that is going to consume those in opposition.”
At 1 John 5:16, 17, John evidently refers to willful, knowing sin in speaking of “a sin that does incur death” as contrasted with one that does not. (Compare Nu 15:30.) Where the evidence indicates such willful, knowing sin, the Christian would not pray for the one so offending. God, of course, is the final Judge as to the heart attitude of the sinner.—Compare Jer 7:16; Mt 5:44; Ac 7:60.
