What type of picture I can put with this sentence, "as spider's web would have to stop fallen rocks"
The simile being developed here is that man is traveling a slippery sloop between life and death, heaven and hell. Edwards wants his audience to feel that there life is as guaranteed as a spider web is guaranteed to stop a falling rock. The image that I picture with this particular simile is that of a large rock falling onto a spider's web, and putting tension on the web so that it is sagging to the point of almost breaking. The rock hangs in the web, with the web suspended low, not quite broken, but clearly having enough stress that the slightest movement or addition weight would cause it to snap.
