You may have heard the saying that there are two kinds of people in the world—
those who divide people into two kinds,
and those who don’t...
We love categorizing things, especially into opposites: land and sea, sun and moon, day and night, light and dark, male and female. And it's easy to read a passage in the Bible and assume that this is how things are. For example, that when God made humankind and it says, "male and female he created them", that this is all there is. There are men and there are women.
Let's step back and take a look at some earlier verses in Genesis 1:
And God said, “Let the water under the sky be gathered to one place, and let dry ground appear.” And it was so. God called the dry ground “land,” and the gathered waters he called “seas.” And God saw that it was good. (Genesis 1:9-10 NIV)
God took one thing (the water under the sky) and divided it into two things. Land. Seas. That's all there is.
But that's not all there is. Land meets sea and sea meets land, and where they do, there are things like marshes, which are not land and not sea. Oh, oh. They are in between, sort of land and sort of water. They don't fit the creation story. Are they bad? Evil? The result of the fall? Or a natural part of God's creation? And what about swamps and bogs?
