LOL... you must not actually listen to Rush much. THAT, is probably the LEAST conceited thing he ever says.
That statement is designed to remind us ALL, that our talents are "given" to us by God... and, it's just a loan. We have a time limit.
I absolutely LOVE that line... and, here you are using it a evidence of Rush's ego?????
Laughable..
He always is referring to himself when he uses the lines, “On loan from God.” But I suppose that goes right by you, in your undying admiration for the man.
