How does the story of Naaman illustrate God's sovereignty?

The account of Naaman in 2 Kings 5, mentioned in the sermon, underscores the expansive nature of God's grace and His sovereignty over whom He chooses to heal and save. Naaman, a Syrian, was not an Israelite, yet God orchestrated his healing when he heeded the words of God's prophet Elisha. This reflects the sovereign choice of God to extend His compassion beyond the boundaries of Israel, which infuriated the Jews listening to Jesus. They struggled with the idea that God's grace could be available to non-Jews, revealing their own misconceptions about being 'chosen.' This serves to illustrate that God is not confined by human categories or traditions and freely gives grace to those whom He elects according to His will, as articulated in Romans 9:15-16.
