Revelation 22:7

7 And behold, I am coming speedily. Blessed (happy and to be envied) is he who observes and lays to heart and keeps the truths of the prophecy (the predictions, consolations, and warnings) contained in this [little] book.

• Remember that all of the things that we have been shown in Revelation: the anti-christ, the false prophet, the 7 Seals, 7 Thunders, 7 Trumpets, the 4 Apocalyptic Horsemen, and  the uncountable number who will be saved all happens in just 3 1/2 years.
• And I will grant the power of prophecy to My two witnesses for 1,260 (42 months; three and one-half years), dressed in sackcloth. Revelation 11:3
• And the woman [herself] fled into the desert (wilderness), where she has a retreat prepared [for her] by God, in which she is to be fed and kept safe for 1,260 days (42 months; three and one-half years). Revelation 12:6
• Jesus will return as a thief in the night, completely unexpected. 
• For you yourselves know perfectly well that the day of the [return of the] Lord will come [as unexpectedly and suddenly] as a thief in the night. 1 Thessalonians 5:2
• What is really a powerful Truth is that people will be saying peace and safety right before He does return to the earth.
• When people are saying, All is well and secure, and, There is peace and safety, then in a moment unforeseen destruction (ruin and death) will come upon them as suddenly as labor pains come upon a woman with child; and they shall by no means escape, for there will be no escape. 1 Thessalonians 5:3
• If everything that will happen in Revelation is physical and not spiritual, do you really believe that people will be saying such things. If everything that we have studied will be physical, then everyone will be looking for Jesus’ return, no one would be caught off guard.
• But if things are great in the world and people are trusting in themselves and wealth, and they believe that they do not need our Father, then they will be caught off guard. The worst condition a person will ever find themselves in is when they believe that they are in control and when they are trusting in worldly wealth. 
• For people will be lovers of self and [utterly] self-centered, lovers of money and aroused by an inordinate [greedy] desire for wealth, proud and arrogant and contemptuous boasters. They will be abusive (blasphemous, scoffing), disobedient to parents, ungrateful, unholy and profane. 2 Timothy 3:2
