A Sea of Symbolism
In Scripture, the sea often symbolizes chaos. This doesn’t mean God was writing a book and he needed a good analogy, so he picked the sea. It means he created the sea as He did so that when Jesus walks on the water it’s written down as a deeply symbolic historical record of Christ treading down chaos and evil, ruling over every aspect of his creation.
Much contemporary scholarship misses this point; conservatives defend a mere history and liberals propound a mere symbolism. Neither gives God the proper glory as the author of Scripture and history, who fills the pages of both with overflowing significance.
