God never said that He would only speak to us today through the Jewish prophets and early Church leaders. In fact, He did make several statements to the contrary. For example:
And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions
The heavens declare the glory of God; the skies proclaim the work of his hands
For since the creation of the world God's invisible qualities - his eternal power and divine nature - have been clearly seen, being understood from what has been made, so that men are without excuse.
And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
And Jesus said unto him, Forbid him not: for he that is not against us is for us..
We are told not to be carried about by every wind of doctrine (Ephesians 4:14). We have the example of the Bereans who compared the new teachings they were receiving about Jesus Christ to the scriptures they already had to see if they were true (Acts 17:11).
We can and should compare prophesies we hear to what the Bible has to say. If the prophesy in question doesn't conflict with established scriptures, we should listen to what it has to say.
The Bible speaks of things to happen in the end times. The prophesies pointing toward that time indicate it is close.
In brief summary, events will lead up to a time of immense suffering and persecution called The Great Tribulation. Afterwards, Jesus Christ Himself will return in bodily form and will rule as absolute monarch on Earth for 1000 years. It will be a time of absolute peace and unprecedented prosperity.
Our Native American ancestors were given prophesies of their own about the end times. They too, speak of great tribulations followed by an unprecedented reign of peace with all mankind living as brothers.
Below is a message describing prophesies of the end times.
