Science progresses and knowledge increases. New ideas are formulated and old ones abandoned. The prevailing science at the time of the Bible was astrology, basically a flat earth geocentric view of cosmology. I would suggest that some of the oral traditions retained in the Bible even predate that. The earth was the entire universe. God walked in the garden, God said come into the ark.
There is little point in running around in circles trying to make the Bible say what it doesn’t say, or to insist that because the Bible says it therefore it must be so. If you trust what science says are you doubting the word of God?
Proverbs 25:2 New International Version (NIV)
2 It is the glory of God to conceal a matter;
to search out a matter is the glory of kings.
Take it that science has searched out what God has concealed. At times they get it wrong, but they are seekers of truth and however reluctantly do have to admit mistakes. It is rarely the Bible must be right, but usually my interpretation of the Bible has to be right.
The test is not what does this actually mean, but is God glorified. I put it to you, what awe, what inspiration, what reflection comes to mind when you consider creation? The problem with flat earth is however accurate the interpretation might be, it does not move with knowledge, and opens the Creator to ridicule. As I see it the first chapter of Genesis demonstrates a movement with knowledge.
Does the modern concept of the universe destroy any concept of an eternal God? Would it make it impossible for Him to send the Saviour? Does it destroy the quality of life found in him? Does holding to outmoded world views, really demonstrate your faith and trust in God?
When Paul preached in Athens he did not give a lesson on how Jesus was the Messiah, but what he spoke was relevant to them. Yes many did laugh at him. The gospel has to be relevant, it has to be for this day and age.
