This Bible Study examines the life and betrayal of Judas Iscariot to illustrate the danger of religious profession without genuine regeneration. It contrasts Judas's outward appearance as a trusted apostle with his inward corruption, highlighting how he remained unregenerated despite years of proximity to Jesus and participation in miracles. The preacher emphasizes that external actions, such as baptism or witnessing power, do not guarantee salvation if the heart remains hardened and self-serving. By analyzing scriptural accounts from Mark, John, and Matthew, the text demonstrates that Judas was a thief and a betrayer whose faith was merely intellectual rather than transformative. Ultimately, the message serves as a solemn warning to believers to examine their own hearts to ensure they are truly born again and not merely counterfeit followers of Christ.
