In Matthew 10:1, we see that Jesus gave His 12 disciples power over unclean spirits, to cast them out, and to heal all kinds of sickness and all kinds of disease. This would include Judas Iscariot, yet Jesus referred to Judas Iscariot as an
unbelieving, unclean devil who would betray Him (John 6:64-71; 13:10-11).
This was no surprise to Jesus. (John 6:64) - But there are some of you who
do not believe. For Jesus knew
from the beginning who they were who
did not believe, and who
would betray Him. Apparently, Judas believed that Jesus' name has the power to cast out demons but did not truly believe in His name (John 1:12) and become a child of God, but instead was the
son of perdition (John 17:12).
Jesus knew what He was doing and was not fooled by Judas. In John 13:18, Jesus explains - I do not speak concerning all of you. I know whom I have chosen;
but that the Scripture may be fulfilled, 'He who eats bread with Me has lifted up his heel against Me.'
Jesus explained in John 13:18. Scripture was fulfilled.
Where does the Bible say that Judas was saved? That is your assumption based on your own human logic and not on Scripture (John 6:64-71; 13:10-11; 17:12).
You call unbelief and betraying Jesus love?
Judas was lost all along and he may have even felt guilty over what he did (worldly sorrow), yet Jesus calls Judas what he truly is -
Judas is a devil! 2 Corinthians 7:10 - For the sorrow that is according to the will of God produces a repentance without regret, leading to salvation,
but the sorrow of the world produces death.
