Can you imagine a world with no air??
or can you even imagine going to a place like a gas station to buy air?
God is awesome that he knew that it would be too expensive for someone like me and some of you..so he made air free.

What is so special about the Air we breath?
It’s oxygen..
“21% of oxygen” is found in our air (http://www.grc.nasa.gov/WWW/k-12/airplane/airprop.html).
Our cells need oxygen.

I know a lot about exercise physiology..
You need oxygen for aerobic exercise..
Our aerobic energy production produces most of our energy that we need for exercise and it is more efficient than the other two energy processes that can function without oxygen.

Apart from exercise,
every cell of our body needs oxygen..
Our Red blood cells has a protein called hemoglobin to carry oxygen.

Oxygen is very important us.
We will talk more about oxygen when we talk about the lungs.
Gas exchange takes place in the lungs..(stay tuned)

God knew that Oxygen is so important to us..
so He added it to air..
Air is Free and easily accessible

How Great is our God.
