There are many things about Judas Iscariot we do not know. After he committed suicide, the Bible says that, “...he went to his own place.” (Acts 1:25) We do not know where this place is. Some think that he will be reincarnated into the Antichrist. We do not know.
We do know that he was not forgiven; he was never saved. Jesus said of Judas, “. . it had been good for that man if he had not been born.” (Matthew 26:24) Judas provides us with a clear picture of the sovereignty of God and the will of man working together. God had, from ages past, determined that Christ would be betrayed by Judas, die on the cross for our sins, and be resurrected. This is what Jesus meant when He said He that all things written in prophecy about Him must be accomplished. (Luke 18:31-33) Nothing would stop the plan of God to provide salvation for mankind.
Jesus says concerning Judas, “While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.” (John 17:12) At one time, Judas believed that Jesus was a prophet, or possibly even believed He was the Messiah. Jesus sent the disciples out to proclaim the Gospel and perform miracles (Luke 9:1-6). Judas was included in this group. It is false preachers/miracle-workers like Judas that Jesus referred to when He said, “And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.” (Matthew 7:23) It is not that they once knew Christ and were saved but lost their salvation. Jesus says, “I never knew you.”
We should be careful in whom we trust and follow.
