How do we know that God's elect will not be deceived?

The assurance that God's elect will not be deceived lies in the promise of the Holy Spirit who guides believers into all truth, as stated in John 16:13. This divine guidance acts as a safeguard against the falsehoods perpetuated by false teachers and the self-righteous. The sovereign grace of God assures that those truly united to Christ through faith will ultimately embrace the doctrines of grace, including total depravity, unconditional election, and the atoning work of Christ. The perseverance of the saints is rooted in God's commitment to preserve His people, as none can pluck them from His hand (John 10:28-29).
