How does the story of Saul and David illustrate God's sovereign choice?

The story of Saul and David serves as a vivid illustration of God's sovereign choice in appointing leaders and ultimately, His people. Saul, despite his initial promise and stature, falls into disobedience and disgrace because of his pride and rejection of God’s commands. In contrast, David is chosen and elevated despite his own failings, illustrating that God's grace is not based on human performance but rather on His sovereign will and purpose. This principle aligns with Reformed theology, emphasizing that salvation is entirely a work of God's grace and not of works (2 Timothy 1:9).
