I found it interesting that Lot recognized the angels that came to his house that day? How were they distinguishable? Did they have a glow? Did they smell "holy"? What was it that Lot "saw"?

I don't know what it was. Maybe God just gave that insightful recognition to Lot. My question is: can I recognize God in everyday things? If not, why? What am I missing? Just something to chew on today.

Genesis 19:1
