"For in six days the LORD made the heavens and the earth, the sea and all that is in them and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it," Exodus 20:11.
The creation account of the universe is the foundation of the Bible. God, in His infinite wisdom, began the account of His word with a non fantastical, straight forward and poetically beautiful account of His great power, knowledge, grace and love proven through His creation of the universe and all that is in it. Six thousand years later, many Christians sit in judgement of God's word and are embarrassed to cling to the biblical six day account of creation. This dispute has great bearing on the gospel itself and is critical to a proper understanding of God's word. I will lay out 3 views of creation briefly and answer them and their implications.
1) Theistic Evolution: this view claims that God created the universe and its basic primordial matter and then Darwinistic evolution has carried the ball since then. It is heretical and not compatible with the gospel of Jesus Christ. Since TE's believe in cavemen, they do not believe in God's direct creation of Adam and Eve which Jesus explicitly states happened in the gospels. Because of this, it is heretical and calls out Jesus Christ as a liar. Their are other implications also like Paul comparing Adam to Jesus and our inheritance of our sin nature through Adam. Many TE's deny a literal Adam and Eve at all and others do hermeneutical gymnastics, like Tim Keller, to explain evolution, a literal Adam and Eve and the relationship of Adam to Jesus and our sin. The main proponents of this heresy are C.S. Lewis and Tim Keller.
2) Old Earth Creationism: There are many variants to this belief but OEC'ers trust in the presupposition of uniformitarianism. They believe the universe is billions of years old and that things change gradually over time. This view is seriously misguided, can have fatal effects for the gospel but is generally within the realm of orthodoxy. OEC'ers put a lot of emphasis on the findings of modern science and often reinterpret much of the first 11 chapters of Genesis to be more secular friendly. One of their major contrivances is to argue that the Hebrew word yom which, is used in Genesis 1, depicts large epochs of time and not twenty four hour days. There is no justification for this, especially considering that Exodus 20:11, cited above, explicitly states that God created the world in 6 days as a pattern for us to follow. This hermeneutic(method of interpretation) has great potential for destruction if consistently applied. For instance, when Jesus was confronted about giving a sign, he did not say, "For as Jonah was in the belly of the beast for 3 billion days and 3 billion nights, so will the Son of Man be 3 billion days and 3 billion nights in the heart of the earth," Matthew 12:40. If we consistently use this hermeneutic, it means we are still waiting on our Lord's resurrection! Furthermore, if we interpret Genesis 1-11 guided primarily according to Ancient Near East customs and wisdom, as so many OEC'ers are apt to do, we can and often do, make a train wreck of the gospel itself. This may be the prevalent view of evangelicals, especially pastors, in this modern age. They often create a creation matrix so fantastical it would make a conspiracy theorist blush. Most often, this view can be laboriously reconciled with orthodoxy. Those associated with it are many. B.B. Warfield was its first modern practitioner and John Piper, John Sailhammer are a couple of its proponents today. It seems to be especially strong in reformed circles.
3)Young Earth Creationism: This is the biblical view that interprets Genesis 1 most strictly to the historical/grammatical method espoused by evangelicals. This view believes that what God said in Genesis 1 was both beautifully poetic and absolutely accurate and true. YEC'ers understand that God's wisdom is foolishness to the world and are willing to look like morons in the eyes of the world. YEC'ers get their name because they believe the world to be between 6 or 10 thousand years old. YEC'ers do not have to do any interpretive gymnastics concerning the gospel and creation. One of the most difficult(perceived) questions that this theory faces is why did God create everything with the appearance of age. This question implies that God is deceptive for creating mountains and stars that are theoretically millions of years away. This question presupposes man's superior wisdom and morality and ignores that God created Adam as a full grown adult, with no belly button.
In a nutshell, and this is a very abbreviated description of these views, theistic evolution is heretical and impugns the gospel because it denies God's direct creation of Adam which causes all sorts of theological conundrums. Old earth creationism is not heretical but silly and if it is carried out to its logical implications, deforms the gospel. Young earth creationism upholds the innerancy of God's word and puts no impediments on the gospel whatsoever. It is foundational that we have a correct view of God's word from verse one through Revelation. Friends, lets learn, live and love the gospel of our glorious Savior.
