Then entered Satan into Judas surnamed Iscariot, being of the number of the twelve. (Luke 22:3)
Some people have speculated that Judas betrayed Jesus in an effort to force Jesus into a confrontation with the Roman government. Then He would have had to use His supernatural power in self-defense and overthrow the Romans thereby giving independence back to the nation of Israel. This idea is based mainly on Judas’ response when he saw that Jesus was condemned. He “repented himself” (Matt. 27:3), implying that the condemnation of Jesus was never his intent. However, the Bible does not say Judas possessed noble virtues. He was simply a thief.
This verse makes it very clear that Satan entered into Judas and was responsible for putting the betrayal of Jesus into Judas’ heart. We can be assured that Satan’s only purpose in motivating Judas to betray Jesus was to steal, kill, and destroy (John 10:10). Moreover, that Satan possessed Judas does not acquit Judas of the responsibility for his actions. The devil goes about seeking whom he may devour (1 Peter 5:8). He cannot devour just anyone. They have to give place to him. By being a thief, Judas gave Satan access to him. He may have never intended to betray Jesus when he began to steal from Him, but once he submitted to Satan in thievery, it was hard to stop.
Sin cannot be controlled. You cannot sin “just a little.” Sin is sin in God’s eyes, and the more you give in to it, the more it captures you. In order to resist the devil and overcome his temptations to sin, you must first submit yourself to God (James 4:7). Once you have submitted to Him, the Holy Spirit will supernaturally empower you to say no to whatever the enemy is trying to do in your life.
