Nelson understood that true freedom is a moral achievement. He therefore spoke morality to the people and they instinctively heard and understood and for a short time the nation enjoyed true freedom.
But then few of our subsequent leaders seem to have understood this, which is why the nation is less free now than it was and the immoralities of the past start to raise their ugly heads once again
And where do we go to find this morality? The Gospel of Matthew chapter 22 verses 36-39 would be a good place to start.
