How do we know our appointment to salvation is true?

The assurance of our appointment to salvation is firmly based on scriptural testimony. Ephesians 1:4-5 declares that God chose us in Christ before the foundation of the world for the purpose of salvation. Additionally, 2 Thessalonians 2:13 states that God has chosen believers for salvation through the sanctifying work of the Spirit. This reflects God's sovereign will in appointing, choosing, and securing believers' salvation through His grace, reinforcing that it is not by human effort but entirely by God's divine purpose.
