So Jesus again said to them, “Truly, truly, I say to you, I am the door of the sheep.  All who came before me are thieves and robbers, but the sheep did not listen to them.  I am the door. If anyone enters by me, he will be saved and will go in and out and find pasture.  The thief comes only to steal and kill and destroy. I came that they may have life and have it abundantly." John 10:7-10 (ESV)
