Paul doesn't just defend God; he points to His own Word as the ultimate authority. What does Scripture say about God's prerogative in mercy?
Paul's defense against the charge of injustice hinges on God's absolute right to extend mercy according to His own will. He appeals to God's own declaration to Moses in Exodus:
God's Declaration to Moses
'I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.' (Exodus 33:19)
This is crucial. God isn't obligated to show mercy to anyone. Our sin makes us deserving of judgment, not mercy. Therefore, when God chooses to show mercy to some and not others, it's an act of grace, not an act of injustice. It’s not based on human merit, will, or effort, but solely on God’s sovereign decision. This doesn’t mean God is arbitrary; it means His reasons are His own, rooted in His perfect character and purposes, which are beyond our full comprehension.
