Doors

Can anyone explain to me why churches may have two, three, four, or more doors in the front of their buildings and yet only one is unlocked on Sunday morning?  I can't tell you the number of times I have visited a church and tried several doors before finding the one that was unlocked.  As frustrating as it to me when that happens it must be even more upsetting to an unchurched person who may have decided to visit a church one morning.  I think the message is very clear...we don't want you in here.  Unless you are a regular member who knows the secret to which door we will open you are not invited.  Locked doors are a major barrier that many churches, both bivocational and fully-funded, have erected to make it difficult for new people to feel welcomed.  At the very least put a large sign on the unlocked door making it obvious that this is the entrance to the church facility.  Better yet, unlock all the front doors if you want to send a message that people are welcomed to your church.
