But today people subtract from the gospel, do they not? They say, 'We can no longer believe the early chapters of Genesis; science proves that they're not true.' Actually, it does not, of course.
'But,' people say, 'evolution disproves Genesis.'But what is evolution? It is just a theory. It has never been proved and it never will be. But why am I concerned about this? It is because the gospel is a unit, a whole, and if you reject any part of it you will be in trouble with all the rest.
It is all very well to say, 'I think man has evolved out of the animals but I am still a Christian, I still believe in the doctrine of salvation.' But how can you? What do men and women need to be saved from? Why do they need to be saved? Have they ever been perfect? Has there been a Fall or not? How many people fell if there was a Fall? No, the whole of the gospel hangs together.
