‘When he prepared the heavens,’ that is the skies, the stars. When God prepared the heavens, I, wisdom, was involved at every stage.
Some things, like this world, where there are very few fixed principles, are changing all the time. And even in false churches things are changing. You think of today when there are so many church goers who want to bring in a new morality, and change all the rules, and change all the principles. But there is a horizon in divine wisdom. There are fixed and settled things that do not change and never change.
