As he sat on the Mount of Olives, the disciples came to
him privately, saying, "
Tell us, when will this be, and
what will be the sign of your coming and of the close of
the age?
"

And Jesus answered them, "
Take heed that no one leads
you astray. For many will come in my name, saying, 'I
am the Christ,' and they will lead many astray. And you
will hear of wars and rumors of wars; see that you are
not alarmed; for this must take place, but the end is not
yet. For nation will rise against nation, and kingdom
against kingdom, and there will be famines and
earthquakes in various places: all this is but the
beginning of the birth-pangs. "Then they will deliver
you up to tribulation, and put you to death; and you
will be hated by all nations for my name's sake. And
then many will fall away, and betray one another, and
hate one another. And many false prophets will arise
and lead many astray. And because wickedness is
multiplied, most men's love will grow cold. But he who
endures to the end will be saved. And this gospel of the
kingdom will be preached throughout the whole world,
as a testimony to all nations; and then the end will
come.
Matthew 24:3-14

There have already been two world wars, and the world
has weapons of mass destruction for the first time.
Furthermore, numerous countries have access to these
weapons for the first time. Every weapon that has ever
been formed has been used. It is foolish to think that we
can avoid what history has proven to be true. That is
why we need God's protection. We can't possibly
protect ourselves without His help.

All of what Jesus describes has been increasing in
number and intensity over the past hundred years. There
have been far more earthquakes, drug-resistant diseases,
plagues, and famines throughout the world than in
previous times. I believe this is just another strong
indicator that the End of the Age is in sight.
