How do we know God will protect His people from deception?

In Revelation 13:8, it is indicated that those whose names are written in the Lamb's Book of Life from the foundation of the world will not be led to worship the beast. This assurance emphasizes God's sovereign grace in preserving His elect from deception. The Scripture reassures us that while false teachers and anti-Christian sentiments may rise, God's hand remains upon His chosen people, ensuring their faith and commitment to Christ will not falter amid trials and tribulations. Additionally, believers are sealed by the Holy Spirit, guarding against being deceived by the lies of false prophets and ensuring their ultimate victory in Christ.
