Why won't the wolf kill the lamb after the curse is lifted?
After the curse is lifted, the wolf will not kill the lamb because the wolf will eat grass and berries and everything else just like other creatures. Scripture says the wolf will dwell with the lamb, so the lamb will not have to worry, and the wolf is not going to kill it.
Les teaches that nature today is laboring under the curse, using the prairie chicken and hawk as an illustration: the hawk's presence means the prairie chicken cannot even blink without danger. But when the curse is lifted, as described in Isaiah chapter 11, the Branch will rule and reign in righteousness and faithfulness. Then the animal kingdom changes: the wolf shall dwell with the lamb. The lamb is not going to have to worry, and the wolf isn't going to kill it, because the wolf is going to eat grass and berries and everything else just like other creatures. Les connects this to what they're looking forward to in Romans chapter 8.
