Jehovahs Witnesses ,The Assembly of God ,The seventh Day Adventists ,The Christadelphians ,The Church Of Jesus Christ Of Latter Day Saints, are just a few of the more well known religions that believe we are living in the last days when Armageddon is going to come.
I am sure with over 40,000 other Christian religions their are quite a few more that would come under that umberella and would have similar beliefs .
Which would also mean they have similar beleifs that millions now living will never die but billions will at Gods Judgement on mankind.
