Like someone said, Jesus has been supposed to be coming "soon" ever since He went back to heaven, so for all we know it could be another 2000 years before He comes. There has always been wars, persecution of people who believe, famine, natural disasters etc
but, as the bible says, we should ALWAYS be ready...
in Gods eyes a thousand years is like one day, and one day is like a thousand years. So tomorrow or two thousand years from now probably don't make much of a difference to Him
