What does the Bible say about false Christs and false prophets?

Mark 13:21-22 emphasizes the reality of false Christs and prophets that will emerge, attempting to deceive believers. These figures may perform signs and wonders designed to lead astray those who are true in their faith. This warning acts as a vital reminder for Christians to remain grounded in the truth of Scripture, ensuring that their faith is not swayed by charismatic but ultimately false teachings. True Christians are to discern all claims about Jesus and align them with the authority of God's Word to safeguard against deception.
