Knock At the Door

I turn on the lights there's a knock at the door. I proceed to the door to look through the peephole. It's 4 am in the morning, and I am not home. How does this person know that no one is home. I've worked so hard not to answer the door. I am reluctant to look through the peephole. But I look and I see someone that I think I know. I see someone I hope to know. I see someone I should know. I see someone I would like to know. I see someone maybe, I've seen before But again, how does this person know that I am not home. I am not home, the store is closed I 'm alone, I am gone, it's been very long I will not open the door, I just can't trust what I do not know. But I'm getting better though, because this time I made it to the door and I even looked through the peephole. Next time I will trust in the Lord, I will open the door.
