Why does doctrine matter?

[PaulKorb]

I have had discussions with some people who claim that doctrine is really not that important.

What is the best response to this statement?

 

[Michelle_Arnold]

Why does the law of gravity matter? Because it is a scientific definition of a truth present in God’s natural creation. In an analogous sense, doctrine matters because it defines a matter of supernatural truth. And, just as science builds upon known truths to make future discoveries, so the development of revelation builds upon known doctrines to further understand supernatural truth.
