Final answer:
King David's life showcases God's calling despite human flaws.
Step-by-step explanation:
King David's life showcases God's calling despite human flaws. Despite his flaws, such as his affair with Bathsheba and orchestrating the death of her husband Uriah, David was chosen by God to be the King of Israel. This is evident in the Bible where God sends the prophet Samuel to anoint David as the future king while he was just a shepherd boy. God saw the potential in David and valued his heart for Him, overlooking his flaws and affirming that it is not about perfection but about faith and obedience.
