How do we know that salvation is God's work from start to finish?

Philippians 1:6 states, 'He who began a good work in you will be faithful to complete it until the day of Christ Jesus.' This verse encapsulates the assurance that salvation is not merely a human effort but a divine work initiated and sustained by God. The biblical narrative reveals that regeneration, or being born again, is entirely a work of the Spirit of God, emphasizing that we as spiritually dead individuals can do nothing to help ourselves. God’s faithfulness ensures that every believer will be brought to the finish line of salvation, confirming that our confidence rests in His promise and ability, not in our actions.
