The Bible describes King David as "a man after God's own heart," and his reign is considered the golden age of ancient Israel. David unified the 12 Hebrew tribes, established a powerful central government, expanded Israel's borders through a combination of diplomacy and military conquest, and laid the foundations for an Israelite monarchy that would endure for centuries. David was far from perfect, however; his fits of temper and sinful behaviors often resulted in tragic consequences. But David's weaknesses, and his trust in the Lord, demonstrate the power of God's forgiveness. King David continues to be a source of fascination and inspiration 3,000 years after his death.
