Read John 13:21-30
When Judas had eaten the bread, Satan entered into him. Then Jesus told him, “Hurry and do what you’re going to do.” – John 13:27 (NLT)
Jesus is troubled for Judas; he is still trying to reach Judas; But at some point, when Judas’ mind is made up and he refuses to change, Jesus allows Satan to enter him. Jesus is always trying to reach us too, but we can push Him away to our own damnation. The only way to avoid this is to keep our trust in God rather than ourselves, and allow Him to continually put to death our sinful nature.
