When There's So Much Light, Why Do I Feel So Dark?

"Come into my chamber," said the spider to the fly.
When the fly was caught within the web, he began to cry,
"Why didn't you tell me, Spider, that I would have to die?"
"You're the one dumb enough to believe my little lie..."

The fly began to struggle, but all his strength was gone,
And Spider danced around his corpse and sang his little song...

Satan is the Spider, and I am the fly
Can someone please help me out of his web before I die?
