I can understand an agnostic position, but it seems to me that
to be an atheist requires just as much faith as a belief in
God.
Agnostic is an adjective and a state of mind so it would be used
to describe someone.
I was going to church thinking about god then i realized that i
was agnostic.
Another example of using agnostic in a sentence is, "How can you
use agnostic in a sentence?"
Technically, you already used agnostic in a sentence. Oops, I
did it too!
