I think it's best if you read it again so I can make sense.
It might be summarized that the poet believes that England brings hopes and glory. People is free. British people are proud of their nation. God protects the land and made the land powerful. God will make the nation even more stronger in the future.
In my opinion, I feel that his “I had a dream” speech was for the future generations. Back in his day,there was segregation and black people were treated very wrong. He wanted his speech to touch peoples hearts so in the future,(now) there wouldn’t be what there once was years ago.
