While physically the things in the world seem to get better,
in that many people don't have to work so hard, due to development
of technology.
It has a lot of drawbacks however.
Industry is polluting the world, so it seems every year,
the number of natural catastrophes is increasing.
The number of mass murders is increasing.
In this year the number of floods and hail strikes was very high,
while the weather is constantly going from one extreme to another,
either too hot or too cold, which was not present even 20 years ago,
when the change was more gradual.
Those verses in Timothy are true, it can be evidently seen in yahoo answers
and other places in internet, which due to lack of direct contact between
people and bad moderation by computer programs, lead to growth of asocial
conduct - hate, people using anonymous to say what they would not do in person,
blaspheming God and Christ, lying and harassing others, daily coming to
unload hate and vile words on each other, while others get mentally ill
and repeat the same questions or post something barely coherent for attention.
Unfortunately the internet and somewhat comfortable life, can make even
Christians lazy and weak in faith, even with the presence of Christian sites
and information is purely moderated with lots of lies and false teachers,
that's why it is easy to isolate yourself, instead of being part of the church
of Lord Jesus Christ, Son of God, and this leads to bad conduct in people,
even if thinking they are Christians, but lacking His love and peace.
Yes, while Christ's power is uniting the world more and undoing the curse of sin,
still at the same time the sin and darkness are growing, since due to the
human technology evil can have wider influence too.
As a person answered below the apostle John was warning people about an antichrist, though there are multiple antichrists, that is false prophets
pretending to be Christ, but bringing evil fruits, rather than goodness of God.
Antichrists try to add lies to the Christian teaching, for example in the past,
they denied that Jesus was really Son of God, or that He only appeared to be
human - to reject His crucifixion and so the payment for sin of the world.
Though in the Bible the final antichrist revealed previously partially in the
figures like Antiochus Epiphanes, who captured Jerusalem, defiled the temple,
and tried to force worshipers of God to reject His law and trying to put himself
as a god.
The same is happenning more and more in history, with figures like
Muhammad, Napoleon, Lenin, Stalin, Hitler all trying to replace Jesus Christ with
themselves, and promoting worship of themselves and the empires (the beast) they
spread, while persecuting Christians.
The final antichrist will have global power, and so will attempt to do the
same thing on global scale - closing churches, forcing people to worship him
and his empire and take the mark of the beast, to join his army for food,
otherwise executing them.
Only then after 3.5 years Jesus will return and will destroy him and his kingdom.
I hope i answered your question, but only God and His son Jesus Christ has the full truth about it.
