It says that courageous action is far more effective than using words.
Student or Learner
Please make the following in red clear. From <<Leading the Life You Want>> by Stewart Friedman.
By the time he finished his dissertatiion, he had become an advocate for using power when necessary to defend the weak. "The great dividing line between words and results was courageous action," he said in his book.
Is this saying "the big difference between words and results was courageous action"? It's rather confusing.
I think the great dividing line represents the hurdle to be surmounted i.e. courageous action required in translating words to yield results.

It makes more sense to me using present tense, thus:
The great dividing line between words and results is courageous action.
