Jesus states that He is the Good Shepherd and then gives the definition of the Good Shepherd. The good shepherd lays down his life for the sheep. Jesus has nothing left to prove in regards to being The Good Shepherd. He already has. Jesus claims in this text that he would wilfully lay down His life for the sheep – He did it. Sin was the greatest threat to Jesus’s sheep and He took that sin upon himself and experienced the most incredible pain and shame through his crucifixion.
