Creation waits for the revealing of the sons of God.

Romans 8:18-21

18 For I consider that the sufferings of this present time are not worth comparing with the glory that is to be revealed to us.
19 For the creation waits with eager longing for the revealing of the sons of God.
20 For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope
21 that the creation itself will be set free from its bondage to corruption and obtain the freedom of the glory of the children of God. – Romans 8:18-21

One day the glory of God will be revealed through us, those who believe in Jesus. The glory of God is revealed in His creation now.  However, creation was also effected by the fall of man. God cursed the ground:

17 And to Adam he said, “Because you have listened to the voice of your wife and have eaten of the tree of which I commanded you, ‘You shall not eat of it,’ cursed is the ground because of you; in pain you shall eat of it all the days of your life;
18 thorns and thistles it shall bring forth for you; and you shall eat the plants of the field.
19 By the sweat of your face you shall eat bread, till you return to the ground, for out of it you were taken; for you are dust, and to dust you shall return.”  – Genesis 3:17-19

Creation waits to be redeemed and to have the curse removed. Creation is subject to futility, pointlessness and uselessness. If the “garden” is not tended it becomes wild with weeds, thistles and thorns. It was no coincidence that Jesus was gives a crown of thorns to wear at the time of His crucifixion. On His head was placed a reminder that the ground had been cursed.  He was being sacraficed to redeem the earth as well as well as mankind. God has a purpose for creation. One day it will also be made new. We are made new in Christ:

Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. – 2 Corinthians 5:17

And at the end of this age God will make a new heaven and earth:

Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and the sea was no more. – Revelation 21:1

Peter mentions the fate of the heavens straight after reminding us that God wants us all to come to repentance:

9 The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance.
10 But the day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies will be burned up and dissolved, and the earth and the works that are done on it will be exposed. – 2 Peter 3:9-10

Creation is growing to see the sons of God revealed. Isaiah prophesied about the change of relationship of man with animals when the Lord returns:

 6 The wolf shall dwell with the lamb, and the leopard shall lie down with the young goat, and the calf and the lion and the fattened calf together; and a little child shall lead them.
7 The cow and the bear shall graze; their young shall lie down together; and the lion shall eat straw like the ox.
8 The nursing child shall play over the hole of the cobra, and the weaned child shall put his hand on the adder’s den.
9 They shall not hurt or destroy in all my holy mountain; for the earth shall be full of the knowledge of the LORD as the waters cover the sea.  – Isaiah 11:6-9

Creation will be set free from bondage and all aspects of creation will reveal the glory of God, through Jesus Christ and the work He did on the cross.
