They recognized the importance of prophecies and recorded the words of the prophets in their sacred writings. Some of the known Biblical prophets were Elijah, Jeremiah and Isaiah. Prophets sometimes predict the future. Sometimes they simply point out what is happening right now. Many prophets do both.
Prophets are honest men and women.
They say exactly what they see, and for this reason they are sometimes not very popular. The Native nations of the Americas have a long tradition of prophecy. Most nations had prophecies that foretold of the coming of Europeans to the Americas. They told of the coming of the explorers from the east, and of course these men did arrive. Another prophecy that is common to many nations of the Americas is the prophecy of the Seventh Generation.
