Even though The Two Witnesses of Revelation 11 might seem irrelevant to those of us who are authentic Christians, for the simple reason that we will be partakers in the Rapture, which will have already happened when the Two Witnesses show up. They come to preach repentance and warn of the judgement that is to come, performing many miracles, signs and wonders in order to warn the people before they lose all hope of an entrance into heaven.
