If it feels a little bit like Monsters, Inc. in this room, it's completely normal. The Door Room is exactly that: a room made out of doors. Why?
In John 10:9 Jesus says, "I am the door."
Revelation 3:20 "Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me."
Matthew 7:7 “Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you.
The Bible is full of allusions to doors, the opportunities they present, and the access they grant or deny.
