This looks like a country singer waking up on the ground from a night of drinking. He only has the dog/horse blanket on him and he has no idea how he got there.
You're closer to right than you know. This is "The Olive Press" by (in)famous white-Jesus Mormon painter Del Parson. The man paints Jesus through a very, very thick lens of the American Mountain West.
For the record, I had to look up the specific painting, but I grew up LDS, and red-robe white-guy mullet Jesus is a Parson trademark.
