Those who heard Jesus use this illustration (of the Good Shepherd) didn’t understand what he meant, so he explained it to them: "I tell you the truth, I am the gate for the sheep.   All who came before me were thieves and robbers. 

          But the true sheep did not listen to them.  Yes, I am the gate. Those who come in through me will be saved.  They will come and go freely and will find good pastures.  The thief’s purpose is to steal and kill and destroy. My purpose is to give them a rich and satisfying life."
