Talk about mixed up. Show me evidence from the Bible that Judas Iscariot was a genuine believer. Judas may have 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). What part of
unbelieving, unclean devil who would betray Jesus (John 6:64-71; 13:10-11) equates to "believing on the Lord Jesus and in His name?"
Luk 14:27 And whosoever doth not bear his cross, and come after me, cannot be my disciple.
Luk 14:33 So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.
Joh 8:31 Then said Jesus to those Jews which believed on him,
If ye continue in my word, then are ye my disciples indeed;
Joh 8:32
And ye shall know the truth, and the truth shall make you free.
Mat 10:1 And when he had called unto him his twelve disciples, he gave them power against unclean spirits, to cast them out, and to heal all manner of sickness and all manner of disease.
Mat 10:8 Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.
Luk 10:1 After these things the Lord appointed other seventy also, and sent them two and two before his face into every city and place, whither he himself would come.
Luk 10:17 And the seventy returned again with joy, saying, Lord,
even the devils are subject unto us through thy name.
Luk 10:18 And he said unto them, I beheld Satan as lightning fall from heaven.
Luk 10:19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
Luk 10:20 Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.
One cannot cast out devils without first believe in or through the name of Jesus.
Mat 10:1 And when he had called unto him his twelve disciples, he gave them power against unclean spirits, to cast them out, and to heal all manner of sickness and all manner of disease.
Mat 10:2 Now the names of the twelve apostles are these; The first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother;
Mat 10:3 Philip, and Bartholomew; Thomas, and Matthew the publican; James the son of Alphaeus, and Lebbaeus, whose surname was Thaddaeus;
Mat 10:4 Simon the Canaanite, and Judas Iscariot, who also betrayed him.
Mar 6:30 And the apostles gathered themselves together unto Jesus, and told him all things, both what they had done, and what they had taught.
Luk 6:13 And when it was day, he called unto him his disciples: and of them he chose twelve, whom also he named apostles;
Luk 6:16 And Judas the brother of James, and Judas Iscariot, which also was the traitor.
Mar 16:17 And
these signs shall follow them that believe;
In my name shall they cast out devils; they shall speak with new tongues;
Mar 16:18 They shall take up serpents; and if they drink any deadly thing, it shall not hurt them;
they shall lay hands on the sick, and they shall recover.
One cannot cast out a spirit or heal the sick without believing on Jesus or in His name.
Mar 9:38 And John answered him, saying, Master, we saw one casting out devils in thy name, and he followeth not us: and we forbad him, because he followeth not us.
Mar 9:39 But Jesus said, Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me.
Joh 14:12 Verily, verily, I say unto you,
He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
Joh 14:13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
Joh 14:14 If ye shall ask any thing in my name, I will do it.
Didn't Judas do the same works as Jesus? Then he believed on Jesus and in His name.
Joh 1:12 But as many as received him, to them gave he power to become the sons of God,
even to them that believe on his name:
Act 16:31 And they said,
Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
Joh 15:4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.
Joh 15:5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit:
for without me ye can do nothing.
Mat 14:29 And he said, Come. And when Peter was come down out of the ship, he walked on the water, to go to Jesus.
Mat 14:30 But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me.
What happened to Peter when he start to doubt or stopped believing on Jesus?
The power of God started to wan.
Judas believe, because he cast out devils and healed the sick.
I say that because the power of God does not work in anyone's life without first believing on Jesus and in His name.
Even as Peter started to sink when He doubted, the same would have happened to Judas if he doubted.
According to your faith be it unto you.
Judas obviously had faith in Jesus to heal and cast out spirits.
