Repent and believe the gospel.
He certainly believed in Jesus.
So do the demons ... they didnt repent either.
He participated in the baptism of others so he must have been baptized himself.
Not sure how you get there ... Judas participated in the baptism of others ... how is that evidence that he was baptized, not to mention saved?
Other than the transfiguration and Resurrection what miracles wasn't he a witness and testimony to?
What are you arguing here? That because he SAW the miracles that Jesus did that he must have been saved?
Can you point to anything that suggests that Judas ever believed in Christ as the Messiah, that he ever repented and believed in Him or demonstrated that he lived under His Lordship? I can list all kinds of evidence that he didnt.
Judas is the perfect example of a false convert. Someone who claims to believe, who plays the part, who knows what to say, who can converse the faith with other people ... but were never regenerated ... because they have never done the one thing that Jesus requires of them ...
Sorry take it up with the other evangelicals.
