Will the wolf still kill the lamb when the curse is lifted?
No. When the curse is lifted, as described in Isaiah chapter 11, the wolf will dwell with the lamb and will not kill it. The wolf will eat grass and berries and everything else just like other creatures, so the lamb will not have to worry.
Les teaches that today's nature labors under the curse, as illustrated by the hawk catching the prairie chicken when it blinked. But when the curse is lifted, as prophesied in Isaiah chapter 11, the branch of verse 1—Christ—will rule and reign in righteousness and faithfulness. Then the animal kingdom changes: the wolf shall dwell with the lamb, and the wolf will not kill it. Instead, the wolf will eat grass and berries and everything else just like other creatures, so the lamb will not have to worry. This is what creation looks forward to in Romans chapter 8.
The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them.
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.
Why won't the lamb have to worry about the wolf in the coming kingdom?
In the coming kingdom, when the curse is lifted, the wolf will dwell with the lamb and will not kill it. Instead, the wolf will eat grass, berries, and everything else just like other creatures. Therefore the lamb will not have to worry, because the wolf is going to eat vegetation rather than prey on it.
