I've always been fascinated by doors. To me, they're more than just the physical entrance to a location; they're the representation of a choice - the choice to enter or to remain outside, to commit to something new or not. Jesus was also interested in doors. In John 10:9, He says, "I am the door." Serving in missions has really taught - and confirmed - to me something about this special Door: we as Christians can't force anyone through it.
