But if the Lord Jesus Christ came already came from Heaven - and everyone saw Him do this - and the wicked were burned away - why hasn't anyone noticed it?Personally I see that is how it has unfolded.
What the world now sees is a result of rejecting the Father.
That is another topic that has been discussed many times.
What will unfold is that, we as humanity, will face a series of Global crisis that are showing us we need to work together as one people.
These convulsions will culminate in a global event, a size an extent that is not known, it is quite possible 2/3 of mankind will not survive, as will not the cities built upon sand.
This event may be of our own doing, either because of war, or because we have mined this earth in such a way, that we aid the shaking of the earth on an unimaginably scale.
Then there are those that hope we will carry in the way we are, that all things are just as they should be.
