Did Jesus need Judas Iscariot who betrayed Jesus in order to pave the road for Jesus to the Cross? No, He didn’t.
Before Jesus chose the disciples, He spent a night praying to God (Luke 6:12). When Jesus chose Judas according to God’s will, Judas was right with God. However, Judas was not right with God as the time went by. It is said that Juda was so trusted by Jesus that he was in charge of the disciples’ treasure. But his iniquity was found as he cheated the treasure (John 12:5-6). This was a turning point from God’s hand to Satan’s hand. Judas gave Satan an opportunity to control him.
The Satan’s first attempt was to avoid Jesus to go to the Cross. After Peter confessed that “Jesus is the Messiah, the Son of the living God” (Mattew 16:15-16), he rebuked and denied Jesus’ death and resurrection which were to come. Jesus immediately rebuked Satan:
“Jesus turned and said to Peter, ‘Get behind me, Satan! You are a stumbling block to me; you do not have in mind the concerns of God, but merely human concerns.'” Matthew 16:23 NIV
Now Satan contradicted himself as he entered into Judas Iscariot and prompted Judas to finish his task by betraying Jesus in order to turn Jesus to the authority (Luke 22:1-6).
Jesus didn’t need Judas to lead Him to the Cross as we read:
“The Son of Man [Jesus] will go just as it is written about him [Jesus]. But woe to that man who betrays the Son of Man! It would be better for him if he had not been born.” Matthew 26:24 NIV
Jesus’ sacrificial death and resurrection have been foretold from the very beginning of the Fall (Genesis 3) throughout the Scriptures. Jesus chose to die and was not killed (Luke 23:46). It was Jesus’ autonomous and initiated act apart from Judas’ betrayal. That’s way Judas’ act was denounced. – T
