How do we know salvation is a continuous process?

David's understanding of salvation encompasses both past and ongoing experiences. In his song in 2 Samuel 22:1-4, he reflects not only on past deliverances but also acknowledges how God continually saves him from his enemies. The theological concept of salvation in Reformed thought emphasizes that while we are justified by faith in Christ's work, we also experience ongoing sanctification and preservation. This means that believers are consistently saved from sin and its consequences throughout their lives. As Paul states in Philippians 1:6, 'He who began a good work in you will carry it on to completion until the day of Christ Jesus,' affirming that our salvation is a work of God that continues for the believer.
