What are you talking about? these thibgs are mentioned in the Bible, we were not made to be in total darkness even though none of us will know when the end will finally come.
"we were not made to be in total darkness"
No, we weren't.
But just because there will be 'sign's, doesn't mean everyone will heed or recognize them. Some may, and some may not.
And even if they did recognize them, most would probably ignore them anyways.
We live in an age where most things that occur, that general fall outside of the 'main stream' thinking are just brushed off as 'natural' or the 'it won't affect me' syndrome.
It's like telling a child not to play in the street because they may get hit by a car.
There answer generally is 'I won't get hit' because they just don't think it could 'happen to me'!
People, in God's eyes, are like children.
And not very well behaved 'children' at that!
