What does the Bible say about Judas fulfilling scripture?

The Bible clearly indicates that Judas Iscariot is a figure of perdition, fulfilling the Scriptures through his betrayal of Jesus. In John 17, Jesus speaks of the security of those the Father has given him, saying that none are lost except the 'son of perdition' (Judas). This emphasizes the distinction between those who are truly saved and those whose hearts are far from God, demonstrating that Judas's actions were known and predetermined by God as part of the divine plan (see Acts 1:16-20). Judas serves as a stark reminder of the reality of apostasy and the consequences of rejecting Christ, showcasing that even in close proximity to the truth, one can still choose darkness over light.
