What does perseverance by preservation mean?

Perseverance by preservation denotes the assurance that believers, those born again in Christ, will remain steadfast in their faith until the end of their lives. This teaching affirms that it is not the believer's ability that sustains their faith, but rather God's sovereign intervention to preserve them. Scripture, such as 2 Thessalonians 3:3, states that 'the Lord is faithful, who shall establish you and keep you from evil.' This encapsulates the essence of perseverance rooted firmly in God's promises and character, demonstrating that His unchanging nature guarantees that His people are kept secure, steadfastly believing until the day of salvation is fully revealed.
