'The formless and empty world of Genesis 1:2 - something that had unity of uniformity - becomes, under God's hand, a diverse unity. It is made good by each part being made different. Over the six days, it becomes a world where things aren't so much like each other as they are for each other. Like a wonderful machine, a complex ecosystem or a human body, the parts all fit each other.'
Rory Shiner, One Forever: The Transforming Power of Being in Christ, p.17.
