Daniel 11

Those who do wickedly against the covenant he shall corrupt with flattery; but the people who know their God shall be strong, and carry out great exploits. And those of the people who understand shall instruct many; yet for many days they shall fall by sword and flame, by captivity and plundering. v.32-33

Read chapter 11
We have another chapter of the still future times that many would call the tribulation.  Comparison of this chapter in Daniel with chapters Revelation will show similarities and both giving certain details of that time to come.   Many people have read or seen the books and movies of the Left Behind series to get their "Christian" view of what the tribulation will be like, yet it's not entire accurate to scripture (one should never take their theology from a movie).  One big thing in the movie and what so many believe is that all the Christians disappear and are not on earth during the tribulation.  This isn't exactly what happens.  We see here that there are still followers of Christ, people who understand the times and instruct many of what must come to pass, they carry out great exploits but also are being martyred.  We also know that many of the believers in Judea at the time disapear, but not into heaven rather they flee to the mountains during this time as in Matthew 25:15-16 says, "'Therefore when you see the ‘abomination of desolation,’ spoken of by Daniel the prophet, standing in the holy place'(whoever reads, let him understand), 'then let those who are in Judea flee to the mountains.'" 
It sometime feels like we're in tribulation times right now seeing how governments all over the world are wicked like what we read in this chapter, yet this tribulation is still a ways off as it will come after the premileenial kingdom we read about in the previous chapter.  Yet we can still choose to respond in either turning against the covenant we have with Jesus due to flattery of our leaders or being strong in God and His understanding in how to live in wicked times till He returns.  Which will you choose or have you already chosen?
