concept [Def.] /ˈkɒnsɛpt/ noun - an abstract idea.
"an idea or invention to help sell or publicize a commodity."
Yes, he got the God as a concept right.
How do you know?
Because we have no direct access to any version of God or gods that people have believed in throughout history.....now if an actual God came forward openly and honestly just like people deal with each other in daily life, that would be a different story. At that point God would not be a concept, but a reality.
