When Jesus says, "I am the door," He is simply putting a choice before His hearers - come through Me or be left out in the cold. There is no more important decision in all of life. There is no more important door. It is the door to life. The door excludes all those who bypass the shepherd. The Pharisees were spiritually blind even though they claimed to have deep spiritual insight. They were false shepherds. They wanted to enter God's sheepfold a different way rather than to trust in Jesus.
