How do we know that God guarantees our salvation?

The assurance of our salvation comes from God's faithfulness to His promises and His sovereign decree of election. Ephesians 1:11-14 emphasizes that we have obtained an inheritance through Christ, 'having been predestined according to the purpose of him who works all things according to the counsel of his will.' This means that our salvation is not based on our efforts or merits but secured by Christ’s atoning sacrifice. As believers, we can trust that God cannot go back on His promises, offering us definitive assurance. Our salvation is a product not only of our faith but of God's sovereign grace and love, as He chooses to save us not because of our works but according to His own purpose and grace, thus ensuring our inheritance is eternally secure.
