This article by Michael Snyder raises lots of good questions. Christians know the answers to them already though. Our Father has told us all this will happen, and He told us that hard times are coming upon the earth, but for those who turn from sin, place their faith in the Messiah Yeshua, and live their lives then on for Him, that they will have eternal life (John 14:6; Acts 4:12; Romans 10:9,10).
And we know who will really rule in the end (Phil 2:9-11, Rev. 22:20).
