And it was so
The most remarkable statement in the creation account is this little phrase. Whatever God wants, He gets. Furthermore, whatever He says is true.
The word translated "so" is כֵֽן (keyn). It is from the verb כּוּן (koon), which means to be firm, be stable, be established. Though pagan kings would claim this status for their laws, it is absolutely true with God's decrees. From the first day on, the Creator spoke and things that came about were perpetuated throughout all of time.
Where a human can direct things to be done ("make it so"), God doesn't delegate. He says "Let (it) come into existence" and it's there for good.
