While I definitely do believe the world as we know it will end, and Christ will return one day, today is not that day. There are several things that are pretty clear in the book of Revelations about what will happen and what is to come first.. However,
"Heaven and earth will pass away, but My words will not pass away.
36"But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone.
37"For the coming of the Son of Man will be just like the days of Noah.
38"For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark,
39and they did not understand until the flood came and took them all away; so will the coming of the Son of Man be.
40"Then there will be two men in the field; one will be taken and one will be left.
41"Two women will be grinding at the mill; one will be taken and one will be left" -Matthew 24:35-41
So, it is coming one day.. But, only God knows the day and hour.
