One world goverment is prophecied about in the book of Daniels, Isiah and Revelations. It gets fairly descriptive in detail and accurate.
According to scripture, one world goverment control is firmly established under anti-christ and lasts 3 1/2 years. It starts out looking very promising but then major attrocities begin being commited and the Christ returns to end it.
Revelations says Christ and those on earth chosen to do battle with the beast. I take this literally to mean a massive rebellion against the attrocities which causes the one world anti-christ goverment to collapse and then a 1,00 year reign of peace.
The United Nations is as anti-christ as you can get. Lets just cancel our support and membership before TSHF?
Let the fighting occur in other countries.
The Lord gave us a brain to use, not to beg for assistance from Him while we sit on our butts.
