How do we know salvation is an ongoing process?

The process of salvation is articulated in three tenses: we have been saved (referring to Christ's atonement), we are being saved (indicating ongoing sanctification), and we shall be saved (denoting the future glorification). This understanding is vital because it shows that salvation encompasses past, present, and future realities. The faithful believer must recognize their continual need for salvation, reflecting on how Peter, despite his close relationship with Christ, also required saving grace, thereby confirming that every follower of Christ must perpetually seek Him for rescue and deliverance.
