The Bible mentions a warning about deception and the emergence of a false leader who will be worshiped as God but is not God, referred to as the Antichrist. This figure is described as the man of sin and the son of perdition. The term 'Antichrist' and 'rapture' are not explicitly mentioned in the Bible but are used to explain these concepts when interpreting the texts. The belief that Christians will be gone before the Antichrist emerges is questioned, emphasizing the importance of being cautious and aware of deception.
