For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope  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. (ESV)
We have a wonderful revelation of God in the Word of God that has been faithfully written down by men who were led by the Holy Spirit. Our Bible shows us exactly who God is. His holy and perfect essence is described in the pages of Scripture. We know of the salvation that is found in Jesus Christ through the holy words of Scripture.
Additionally, we know that Creation has a role to play in revealing the divine nature and character of God. Psalm 19 tells us that the heavens declare the glory of God. Even Jesus said in Luke 19 that if the disciples did not give him glory the very stones would cry out. Creation plays a significant role in showing forth the glories of God.
Sadly, Creation is somewhat handicapped in how well it is able to declare God's glory. The effects of mankind's sin has brought bondage to corruption. The Earth was originally designed to absorb rain and seeds and gifts from God. Because of sin it has absorbed the blood of murdered men and women. It has been ravaged by the wars and killings of mankind.
Creation longs for the freedom that can only come from God when he sets man completely free from all of the effects of sin and degradation. Just like mankind looks forward to ultimate redemption and freedom, so also the Earth looks forward to this as well. It is important to note that the cause of all corruption is the sinfulness of mankind.
Our lesson from nature can be very informative. We need to look to God for our ultimate freedom. Our sin brings corruption both to man and nature. Repentance places us in a position of hope, as we look forward to ultimate redemption for man and nature.
