"This know also, that in the last days perilous times shall come. For men shall be lover of their own selves.." 2 Timothy 1-2
perilous times is the end time that we are in now! It is the most difficult times in the history of this world!
Because Satan knows that the end times is here, and he knows that he has a short time. So all he is after is to make things to be very difficult. So that countless people in the world can go to perdition. And so that even believers in Christ can compromise their faith, and thereby come short of heaven.
