How do we know that final perseverance is true?

The doctrine of final perseverance affirms that those who are genuinely called and saved by God will endure to the end. This belief is undergirded by passages like Philippians 1:6, which states, 'He who began a good work in you will carry it on to completion until the day of Christ Jesus.' It highlights God's commitment to His elect, assuring that their salvation is secure. Additionally, John 10:28-29 evidences that Jesus promises eternal security for His sheep, declaring no one can snatch them from His hand. Thus, final perseverance reflects the certainty of God's promises and the transformative work of the Holy Spirit in believers to keep them steadfast in faith.
