This message contrasts Jesus, the door of the sheep and the Good Shepherd with all who have preceded Him and shows that He alone is able to give abundant life, a life that begins here, but continues into eternity. This life is not simply for the people of Israel, but for all who will believe in Him.

10 The thief comes only to steal and kill and destroy. I came that they may have life and have it abundantly.
John 10:10 English Standard Version (ESV)
