The Shepherd Door
In John 10 Christ described himself as the Good or Noble Shepherd. At the same time he said he was the door of the sheep. It looks like he is mixing metaphors. Yet when we take a closer look at the culture of the time, it was not unusual for a shepherd to take his flock into an enclosure and then sleep at the entrance to the sheepfold and become a human door.
"I am the door; if anyone enters through Me, he shall be saved, and shall go in and out, and find pasture. "The thief comes only to steal, and kill, and destroy; I came that they might have life, and might have it abundantly. (John 10:9-10)
The noble shepherd is the door so as to protect the sheep. When the sheep go out, he has to go with them. Then, he is the shepherd again. This shepherd not only protects and makes sure the sheep are fed, he is also committed to them so that they have an abundant life. He is so committed to his sheep that unlike the thief, he does not take the life of the sheep he gives his life for the sheep.
Our salvation, as with the sheep and with us, depends on the faithfulness of the shepherd. Sheep cannot survive except with a faithful shepherd, nor can we.
