I am the good shepherd: the good shepherd giveth his life for the sheep. (John 10:11)
In the last “I AM” statement, Jesus said He was “the door” – the only way into the sheepfold. We also learned that a porter guarded the door by physically placing himself across the entrance (John 10:3). In essence, the porter became “the door.” In the absence of a porter, the shepherd himself would perform this task making himself the door (John 10:9).
