The Babylonian exiles were learned men. Their audience, however, were the people who needed to remember what God had spoken to Abraham those many years ago. Mesopotamian sacrifices, seven days, servitude in Egypt, rain from clouds that floated in the blue waters above. But the story was different from the other myths. This myth was to become flesh.
The scribes had memorized the texts and didn’t stray from meaning. Genesis was a folk tale like the others. The story changed over time, until the final, by-heart version was written down by an inspired person. Its essential truthfulness preserved a collaboration between God and man.
As with Lewis, the complete story of Christ was myth come true. Earlier pagan myths foreshadowed Him. Historicism can hinder the story. The ancients’ moral worldview related Eden as a sanctuary like the temple and tabernacle. The Israelites were heirs of Adam. Abram was God’s fresh start after Adam. We all long for Eden. Read and remember.
