I recently had a conversation with a couple of my colleagues that revolved around Creation and our views based on what the Bible says. This short clip below of John Piper on "What should we teach about Creation?" captures the essence of this conversation well. My two colleagues who I love dearly both held to a more six literal day creation, whereas I, like Piper, am more comfortable with John Sailhamer's view. His view is that all creation happened to prepare the land for man.
As Piper says in the video, "In verse 1, 'In the beginning he made the heavens and the earth,' he makes everything. And then you go day by day and he's preparing the land. He's not bringing new things into existence; he's preparing the land and causing things to grow and separating out water and earth. And then, when it's all set and prepared, he creates and puts man there."
"So that has the advantage of saying that the earth is billions of years old if it wants to be—whatever science says it is, it is—but man is young, and he was good and he sinned. He was a real historical person, because Romans 5 says so, and so does the rest of the Bible."
