God promises a startling change in the condition of the mountains and plants and fields when Messiah comes to reign. There will be a marvelous transformation of this old fallen, broken down world, marred now by sin and corruption.In Isaiah 11, the change in the animal's behavior is underlined: where once there was discord and death and danger, Christ's reign will bring about peace and friendship and docility. The wild beasts will be tame in the hands of a little child! The lion will eat straw like an ox, and the beasts will no more destroy each other!In other words, the animals will no longer behave according to the fallen and corrupt world.According to God's explanation, the reason for this dramatic change is, that the whole world will be filled with the knowledge of God, like the water covers the sea!The overwhelming knowledge of God from the presence of Jesus Christ will overcome the corruption of sin, and will rule the behavior even of the animals!Paul used the promise of the glorious restoration of the creature by the promised glorification of the sons of God, as an illustration of the wonder of the comfort we have by the Holy Ghost, that we shall one day be glorified. If the animals, so much more the Lord's people themselves!Jesus made similar arguments about how God cares for the needs of the animals, so much more will He care for His Children!He uses the life and death of sparrows to show God's greater care for us! "Not one sparrow is forgotten before God! Fear not therefore, ye are of more value than many sparrows!"Christ goes further, noting that God provides the food and clothing and shelter for His animals, and therefore He will provide for us!
