What does the parable of the lost sheep teach about God's grace?

In the parable of the lost sheep found in Luke 15, Jesus teaches that God's grace is not passive but actively seeks out those who are lost. The shepherd's willingness to leave the ninety-nine signifies the value of each individual in God's eyes. This parable highlights the truth that all humanity, like sheep, have gone astray, and only by His grace are we able to return. The shepherd’s joy over finding the lost sheep reflects the heavenly celebration when a sinner repents. Therefore, this parable serves as a powerful reminder of the individual attention and care God extends towards each of His elect.
