What does the Bible say about everlasting salvation?

The concept of everlasting salvation is a profoundly reassuring theme in scripture, exemplified in Isaiah 45:17, where it declares that 'Israel shall be saved in the Lord with an everlasting salvation.' This implies that true salvation, wrought by God, is eternal and cannot be forfeited or lost. This everlasting aspect indicates that salvation is not dependent on human effort but rather is a sovereign work of God that is guaranteed to the elect. The assurance that believers will never be put to shame or confounded stems from their secure position in Christ, who effectively redeems and preserves them for all eternity.
