Wars, earthquakes and pestilences are not signs of Christ’s return.
Matthew 24:6 And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet. 7 For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. 8 All these are the beginning of sorrows.
There are 2 events prophesied which lead to the return of Christ.
One is in Ezekiel 38 and 39.
This requires Israel to experience a period of peace prior to an invasion from the north – further details are given in Zechariah 10-14. Since 1948 when Israel was re-established as a nation, it has known no peace.
The second is in Revelation 17
This requires the nations of western Europe to surrender their sovereignty to a single government as described in Revelation 17. It requires a European army. During the gathering of the nations to Armageddon (which is almost certainly the same event as Ezekiel 38 and 39) Christ returns as a thief to gather his elect.
The European union required the exit of Britain to move towards a political union.
We may see with hindsight that the current pandemic will facilitate both a period of peace for Israel and a political union of Europe.
Luke 21 has a dual fulfilment
Luke 21:20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. 21 Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. 22 For these be the days of vengeance, that all things which are written maybe fulfilled.
To watch for Christ’s return, we must watch Israel.
I hope you find this helpful.
