cold and homeless and I don't feel safe to help....

So, I am sitting in my office at church and am the only one here. I am working on my sermon and other things...and the doors are locked--to my office, and outside. The church, although in a nice part of town, is at the intersection of many bus stops and through routes, and next to a park, so we get some traffic from people seeking assistance. It is also a bitter cold rainy wintery day. This young man, outside my window, is trying to get into the door that really isn't ever open. So we talked through my window. He said he was looking for help...and I said I couldn't help him right now. I told him he could come back for AA later on. He wanted the "preacher" (obviously I WASNT the preacher, b/c I wouldn't let him in). He asked if there was a library, or if he could at least come in. He was cold, and I don't blame him. I pointed him to the public library. As the only person here, and as a woman, I just didn't feel safe. I know that most transient people are not dangerous, but I just couldn't let him in to hang out. I feel guilty...in spite of knowing it was the right thing to do--I have done this in the past, but this was the worst weather ever I have had to turn someone away. It feels even hypocritical to offer a prayer for him...but God, please...forgive me...and help him find warmth on this day.
Amen.
