The evil one hasn't come yet in the form of the antichrist, but Paul says that he is coming, and that he will cause chaos in our world.
But this is secretly happening already, and all the persecutions and murdering of Christians around the world is apart of this event that will happen soon in the future.
He will bring with him destruction, lawlessness and disregard any worship to any God except himself.
Some people may say that the day of the Lord is already here because of a dream they may have had or similar...DON'T me fooled, the Lord had not come yet. We will know quite clearly when the Lord will come in a Glorious appearing.
We will also know beforehand the events that will occur before the second coming of the Lord, as they are stated in this chapter.
Here are a few points: (according to 2 Thessalonians 2)
- The antichrist will rise and will place himself in the temple of God and treat himself as God.
- This man will come and create lawlessness and do the work of satan. He will persecute Christians who believe in the 'real' God.
- He will use every kind of evil deception to divert the Christian's attention from God.
- He will perform counterfeit miracles, which some may think is from God but they mean nothing and they are evil
There are a whole bunch of events that need to happen. Here is a link to a chart that plots the events. These events are mentioned in many prophecies, repeated in many books of the bible and some are already happening.
Be ready for Christ, be prepared for the events leading up His coming and know that He is coming QUICKLY!
