Seriously! The most expensive things we buy are things that humans create - technology. The cheap things? Usually what is provided by God in nature.
We really need relatively few things to live - air, water, food, shelter, clothing. Think about it. All of that is provided directly from the earth by God. That is why people survived for so long without any technology.
Air? Check! We don't even have to think about that.
Water? Check! We have bodies of water all over that we can get liquid from.
Food? Check! Look around, we have trees with fruit, bushes with berries and plenty of other plants that grow from the earth. Animals are everywhere that provide food for us, even the non-domesticated kind.
Shelter? Check! It might take a little work, but we still build with natural ingredients like wood. Even bricks and concrete are made from stuff right from the earth.
Clothing? Check! Yet again, it takes a little work but our cotton clothing comes from the earth. Even leather comes from animals that God provides.
I don't think we realize just how well God takes care of us. So, thanks God for covering all our basic needs so easily!
