What does the Bible say about Judas Iscariot's betrayal?

Judas Iscariot is depicted in the Bible as a disciple who was physically close to Jesus, participating in His ministry and even performing miracles in His name. However, despite this outward association with Christ, Judas never truly believed in Him or loved Him, ultimately betraying the Lord for thirty pieces of silver (Matthew 26:14-16). His actions highlight the reality that one can outwardly participate in the kingdom of God yet remain spiritually lost, demonstrating the profound depravity of the human heart and the necessity for divine grace for true salvation.
