Behold

I was awoken to look at what seemed to be a dream, as I looked I was entering a big building through a side door as were many people. I noticed the main entrance facing the street was hardly being used, strange I thought, intrigged by this I stood at a window watching a few come straggling in that main door.There standing on the outside is a person who I could see as these shodow's of other's would take out a key and let themselve's in as they entered around the strange person standing by the door. I thought He was a door man or a greeter, but He never once openned the door for any of those that entered and they would quickly close the door not letting the stranger sneak in behind them, pecqullier I thought!
My attention was drawn to some commotion going on in the autatorium where a host of shadowy figure's were milling about, not really doing anything that looked inviting, but I wandered in to see if I could get involved, but was turned aside because I wasn't able to show a key.
There are hundreds of people coming into the main room through side door's from four corner's of this big room but they too are standing around the outside looking in at what appear's to be three or four separate groups or team's, if they are some kind of team? It's totally clear that they are not working toward any particular goal, and the team's roster is full, because as others try to engage, they are also turned away for lack of having a key, It's like the one's in the middle know we are in the building, which they don't seem to mind, but at the same time they know who possess key's and those who do not.
There is some kind of belonging that I can't put my finger on and some strange feeling of wanting to belong without invitation it's obvious you will not be welcomed to these special team's what ever they are.
There is a familiar sound coming from the main entrance, a tap, tap and another tap, no one seem's to hear it although everyone standing around that are not part of the festivities know someone want's in, why? I wonder doesn't He come around to the side door, we got in that way, although clearly not welcome we are in.
Ignored by all that entered with a key none would let Him in until all inside heard the one still patciantly standing at the front door, in a quite yet audible voice say"Behold I stand at the door and knock."
Is someone going to let him in the building at least?
