What does the Bible say about salvation being from the Lord?

In the book of Jonah, we see a clear illustration of salvation's divine origin. Jonah's confession, 'Salvation is of the Lord' (Jonah 2:9), emphasizes that it is entirely God's work to save His people. This aligns with the broader scriptural teaching found throughout both the Old and New Testaments, such as Ephesians 2:8-9 which states that salvation is a gift from God, not a result of our own works, so that no one may boast. The experience of Jonah illustrates that even in rebellion and dire circumstances, God's purpose prevails, demonstrating that salvation is not dependent on human effort but is a gracious act of God.
