What will the earth be full of in the future kingdom?
The earth will be full of the knowledge of the Lord, as the waters cover the sea. In that future kingdom, nothing will hurt or destroy in all God's holy mountain. The curse will be lifted, and creation will finally experience the peace and restoration God intended.
Les explains that in the future kingdom the curse will be lifted, so predator and prey will pasture together. The leopard will lie down with the kid, the calf, the young lion, and the fatling; a little child will lead them. The cow and the bear will feed together, their young will lie down together, and the lion will eat straw like the cow. A nursing child will play safely on the hole of the asp, and a weaned child will put his hand on the cockatrice's den—no fear. Les connects this to Romans 8, where the whole creation groans and travails in pain until now, waiting for the curse to be removed. Believers, who have the firstfruits of the Spirit, look forward to that day, while unbelievers shrink from it. The earth will be full of the knowledge of the Lord as the waters cover the sea, and Christ will intervene to set things straight.
They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea.
