How do we know salvation is certain?

The certainty of salvation is grounded in the sovereignty of God, as indicated in 2 Thessalonians 2:13, where Paul affirms that God has 'chosen you to salvation.' This emphasizes that God's salvation is particular and intentional, not merely a hopeful offer to all. The message of grace in Scripture reveals that God saves those He elects, and not everyone will be saved, reinforcing that salvation is not left to chance or human will. The crippled man at Lystra illustrates this, as God intended to save him specifically, highlighting that salvation is entirely of the Lord and rooted in His divine purpose.
