One of the biggest differences between evolutionary thinking and creationists thinking is the issue of purpose verses purposelessness. The arguments and points for creation based on the testimony of the Bible shows that God had a purpose and a plan during creation, which reveals that He has a purpose and plan for His creation. In contrast, the ideas presented by evolutionists (especially those that remove God from the process of evolution), show that life came from random chance, thereby suggesting that life itself is random and governed by chance. These two thought processes can cause people to live very differently, so understanding the Bible and how it defines life's purpose is critical for the believer in the Bible.
Evidence of God's plan for His creation exists in every detail of the creation account. However, one of the facets of His work that provides a powerful proof of God purposing His creation come from the work He did in the 2nd day. In Genesis 1:6-8 the Bible documents the work that God did in the second day. Genesis 1:6-8 states that God created a "firmament" or an "expanse." The original Hebrew word and root meaning of the word means "to spread out," which suggests something along the lines of a dome being formed over the earth. Genesis 1:6-8 reveals that this dome was made of water. Thus, the second day of creation shows that the world was made up of a newly formed mass of water that had light shinning on it from God alone, the Holy Spirit hovering over the water, and then God placed this dome of water around the ball of water that was freely floating in space. Many Bible scholars and teachers have traditionally referred to this "expanse" as the atmosphere of the earth - especially since the end of Genesis 1:6-8 says that God called the expanse "sky." Understanding then, that God created this water atmosphere around the earth, one can find purpose in God's plan.
One of the fundamental purposes of the atmosphere that surrounds our planet today is protection. Our atmosphere protects life on the planet from harmful substances and materials that are out in space. It is a shield of sorts that permits useful elements to remain on this earth, and keeps many harmful elements out of the world. Therefore, the second day of creation shows that God placed a protective layer around the world. However, God has not yet placed anything in the world. What is God seeking to protect? When one continues on in the creation account, one will find that God's most precious element of creation, regardless of its size and magnitude compared to the rest of His creation, is mankind. Therefore, as one examines the creation account as it leads up to the creation of humanity, one will find that God is essentially building a dwelling place for the human race. God is preparing a place for His people and special treasure. God is constructing a livable environment, and before He places His children in this world, He is making efforts to provide protection, nourishment, and other things that are essential to life.
The Bible teaches that God desires life for His children, and as God provides a protective layer of water around the planet that He created for His children to dwell in, one can see that God is careful to ensure the life of His children. While the protective layer of atmosphere doesn't exist in the same way today (because of the flood that God used to judge sin), the order in which God created certain things reveals that God has a plan in His mind that He executed to perfection. One does not create a mechanism to protect unless one has something in mind that one has a desire to protect. One does not typically desire to protect something that is valueless and meaningless. Thus, the Bible shows that God considered His creation valuable and for this reason desired to protect it. Many other theories that do not come from the Bible suggest that the placement of these protective devices in the natural world are simply accidental as certain circumstances had just the right ingredients over long periods of time to facilitate the production of useful facets of life in an order that just so happened to work out.
Though this summary is a gross over-exaggeration of certain secular theories, the point is that one argument is based on random chance and accident, while the Bible provides great evidence that God created with purpose and since He has purpose, God's creation is in a position of need to discover that purpose and live according to it since He is Creator. Thankfully God not only provided evidence of His purpose in the Word, but goes great lengths to explain His purpose throughout the course of the Word as well. Life seems meaningless and purposeless for many people. However, Genesis 1:6-8 reveals that purposeless is not on the mind of the Living God who created the heavens, the earth, and everything in it. The Bible shows that God has a plan. One must then seek Him to know what that plan is. Based on the first 8 verses of the Bible, it does not appear that God is seeking to hide and disguise that plan. The Bible shows that God is willing to reveal His plan so long as we are willing to humbly seek Him to understand His plan for His glory.
