The mainstream Church teaches about the antichrist and the 7 years. Take a look at  Daniel chapter 9 verse 27.  Instead of thinking antichrist like the church says think Jesus. That verse says He will confirm a covenant with many for one seven. In the middle of the seven he will put an end to sacrifice and offering. Jesus ministry lasted 3 1/2 years. At the 3 1/2 year mark he became the sacrifice. In other words He put an end to the sacrifice. The Jews rejected Him and they continued the sacrifice which was an abomination before God. 3 1/2 years later Peter saw something that looked like a sheet fill of unclean animals. From that Peter saw that the gospel was for everybody. Jesus 3 1/2 years died and rose again. Plus 3 1/2 years the gospel only when to the Jews. That was the final seven years. If you are using the NIV bible look at the footnotes for verse 27.  You should be able to see what I am saying...Daniel 9:27 Or And one who causes desolation will come upon the wing of the abominable temple, until the end that is decreed is poured out on the desolated city  You can read about he seventy sevens including the last seven starting in verse 20 of the same chapter.  Notice what the Angel Gabriel said in verse 24. Seventy sevens are decreed for YOUR people. This is not talking about the end of the world. It is talking about the special mission the Jewish people had from the time of Abraham.
