How do I know you ask. Well to put it simply, it's all in the Bible you duts. And how do I know it's true? It's in the Bible too. Not once, not twice, but thrice as in says so in Matthew 24, Mark 13 and Luke 21.

"⁸He replied: "Watch out that
you are not deceived. For many will come in my name, claiming, 'I am he,' and,
'The time is near.' Do not follow them. ⁹When you
hear of wars and revolutions, do not be frightened. These things must happen
first, but the end will not come right away."

¹⁰Then he said to them: "Nation will rise against
nation, and kingdom against kingdom. ¹¹There will be
great earthquakes, famines and pestilences in various places, and fearful events
and great signs from heaven." "

Luke 21 : 8-11

In verse 8, they are obviously refering to the false christ who is coming in October, and he is only just one of the many that is to come. In verse 9 and 10, they are refering to the Iraq war. On verse 11, they are refering to the many recent natural disasters that took place recently. And they even have evidence of the tsunami :

²⁵ "There will be signs in the sun,
moon and stars. On the earth, nations will be in anguish and perplexity at
the roaring and tossing of the sea."

Luke 21 : 25

There will be no escape ( Luke 21 : 21-22), but still, we must keep watch, as
this is Jesus' command.

"²³So be on your guard; I have told
you everything ahead of time."

Mark 13 : 23

³⁵"Therefore keep watch because you
do not know when the owner of the house will come back—whether in the evening,
or at midnight, or when the rooster crows, or at dawn.³⁶If he comes suddenly, do not let him find you sleeping. ³⁷What I say to you, I say to everyone: 'Watch!'

Mark 13 : 35-37

But I am not afraid.

"Heaven and earth will pass away, but my words will never pass
away."

Matthew 24 : 35, Mark 13 : 31, Luke 21 :33

Even so, come, Lord Jesus. Amen.
