The Bible teaches that God's choice to show mercy is rooted in His sovereign will and eternal purpose, as seen in Jonah and throughout Scripture.
The doctrine of divine election in the Reformed tradition emphasizes that God chooses individuals for mercy based on His sovereign will rather than any foreseen merit or action on their part. In Jonah's story, God's decision to show mercy to the Ninevites was predetermined and made manifest through Jonah's preaching. This reflects God's overarching plan of redemption where He has eternally purposed to glorify Himself in the salvation of a people chosen from all nations. Romans 9:15-16 affirms this by stating, 'For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.”' The narrative of Jonah exemplifies this principle, asserting that God’s mercy is given freely according to His grace and mercy, which is unmerited and unconditional.
