How does the story of Elijah illustrate the concept of grace?

In the account of 2 Kings 3, God's grace is displayed in how He provides for the sinful kings through the prophet Elijah. Despite Jehoram's idolatry and his reliance on false gods, God chooses to show mercy because of Jehoshaphat's presence, which symbolizes God's grace in action. This reflects the Reformed understanding that grace is not based on human merit but on God's sovereign choice and the intercession of Christ, who makes believers acceptable before God. Therefore, we see how God’s mercy operates through His designated means, illustrating that grace is a gift from God, not a result of our actions.
