What do they mean by their song 'People Get Ready", Jeff Beck and Rod Stewart?

The gospel-influenced track was a Curtis Mayfield composition, and displayed the growing sense of social and political awareness in his writing.

Mayfield said, "That was taken from my church or from the upbringing of messages from the church. Like there's no hiding place and get on board, and images of that sort. I must have been in a very deep mood of that type of religious inspiration when I wrote that song."

This should cover it.
