How do we know God keeps His people saved?

In 1 Corinthians 1:8, Paul states that God shall confirm His people until the end, ensuring they are found blameless on the day of the Lord Jesus Christ. This promise demonstrates God's faithfulness and power to preserve His elect. Passages like John 10:27-29 affirm that no one can snatch them from His hand, underscoring the belief in the perseverance of the saints. Furthermore, Philippians 1:6 reassures us that the work God begins in us will be completed. This certainty is rooted in God's unchanging nature and His commitment to His covenant people.
