How does Jesus illustrate His mission to save the lost?

In the parable found in Luke 15:3-7, Jesus compares Himself to a shepherd who leaves the ninety-nine sheep to search for the one that is lost. This not only highlights His active pursuit of sinners but also emphasizes the value of each individual to Him. When He finds the lost sheep, He rejoices, reflecting the heart of God that delights in the salvation of sinners. This narrative serves as the foundation for understanding the purpose of Christ's coming; He seeks and saves the lost, demonstrating that no one is beyond His mercy and grace.
