How do we know the perseverance of the saints is true?

The doctrine of the perseverance of the saints is grounded in the unchanging nature of God and His covenant promises. Philippians 1:6 assures us that He who began a good work in us will carry it on to completion until the day of Christ Jesus. This doctrine is linked to the idea that true believers, who have been regenerated and given spiritual life, will exhibit faith and obedience as evidence of their salvation. Furthermore, it is by God's sovereign grace working within them that they are empowered to fulfill His will and bring glory to His name. Therefore, the perseverance of the saints is not dependent on human effort but entirely upon God's fidelity and grace.
