The evening meal was in progress, and the devil had already prompted Judas, the son of Simon Iscariot, to betray Jesus. John 13:2
Throughout the Gospels we see a common thread regarding Judas Iscariot and that is one of betrayal. He was greedy with the funds they collected, and he was ultimately greedy with handing Jesus over to the Jewish leaders. He is categorized differently than his fellow Disciples. Even though they had their faults and doubts and blemishes, you could not question their loyalty. Even later when they scattered for fear of their own lives, you see contrition and regret over their actions. In fact, you are reading this because of their actions after they ran scared from Jesus!
But Judas, on the other hand, wasn’t a loyal follower. I can’t say for sure but he was probably in it to make a buck or two.
The thing, though, that has puzzled me for the last few years is the fact that Jesus chose Judas as one of the Twelve. Jesus knew Judas’ massive character flaws and still chose him.
Similarly, God knew our massive character flaws and still chose us. It makes no sense to me. None whatsoever.
