A relevant passage in the gospels is as follows [0]:
> Now as He sat on the Mount of Olives, the disciples came to Him privately, saying, “Tell us, when will these things be? And what will be the sign of Your coming, and of the end of the age?” And Jesus answered and said to them: “Take heed that no one deceives you. For many will come in My name, saying, ‘I am the Christ,’ and will deceive many. And you will hear of wars and rumors of wars. See that you are not troubled; for all these things must come to pass, but the end is not yet. For nation will rise against nation, and kingdom against kingdom. And there will be famines, pestilences, and earthquakes in various places. All these are the beginning of sorrows.
> “Then they will deliver you up to tribulation and kill you, and you will be hated by all nations for My name’s sake. And then many will be offended, will betray one another, and will hate one another. Then many false prophets will rise up and deceive many. And because lawlessness will abound, the love of many will grow cold. But he who endures to the end shall be saved. And this gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come.
Regardless of one's faith, from reading this text it is apparent that things would need to get substantially worse than they are today to warrant the return of Christ. In particular the part about being delivered up to tribulation--similar persecutions have happened in history but the scale necessary for such an event as described would be immense.
"The Dajjal will imitate the miracles performed by Jesus, such as healing the sick and raising the dead, the latter done with the aid of demons. He will deceive many <...>"
As for the time of events, I find this the most compelling:
Earth's polar axis slowly rotates, with a period of 26,000 years. This period is divided into 12 ages: the age of Aries, Pisces, Aquarius and so on. A lot of christian symbology revolves around sheep and fish. Symbolically speaking, 2000 years ago, Aries died to begin the age of Pisces. Similarly, in around 2150, Pisces will yield to Aquarius.
It's also interesting that the age of Aries is considered the last age of the 12, after which the next great cycle begins (see Pistis Sophia). Whether this has astronomical foundation is a question.
