Remember that the Philadelphian Church (The Revelation 3) was promised that God would care for us during "the hour of trial which is coming on the whole world, to try those who dwell upon the earth". This word "trial" speaks of extraordinary pressure, which does not merely evoke a response, but actually forces one. We understand through recent natural disasters, that such calamities draw forth from some greater goodness than expected; while in others hitherto hidden depths of evil are discovered.
Also the calamitous events pummeling the world at that time are called (Rev 6.16), "the wrath of the Lamb".
We see this dichotomy most clearly in events which befall Israel immediately before Jesus' "feet shall stand on the Mount of Olives", and He "will become king over all the earth" and all the nations shall begin to go up to Jerusalem to worship Him "the King, the Lord of hosts". (Zec 14.4,9,16)
It will be an horrific and awful time for God's Jewish People everywhere, but most especially in The Land and in Jerusalem. There, simultaneously, satan will seek to destroy them and the Lamb's indignation over their apostasy will be expressed.
"I will gather all the nations against Jerusalem to battle, and the city shall be taken and the houses plundered and the women ravished; half of the city shall go into exile, but the rest of the people shall not be cut off from the city." (14.2)
"But when you see Jerusalem surrounded by armies, then know that its desolation has come near...for these are days of vengeance to fulfill all that is written...For great distress shall be upon the earth and wrath upon this people." (Lk 21.20-24)
But because all of this occurs under the purview of the New Covenant, satan's power is heavily proscribed and God's indignation over Israel's failure and backslidings is of the Lamb and therefore unto salvation. So, in the midst of the chaos and destruction there will come into our ears glorious and almost unbelievably good news. That even as satanic persecution and divine displeasure are let loose, God has opened Heaven over His 21st C Children of Abraham and is flooding them with His Holy Spirit of grace and intense prayer. (Zec 12.10)
Thus is splendidly and timely fulfilled that most ancient of Moses' prophecies, "When you are in tribulation, and all these things come upon you in the latter days, you will return to the Lord your God and obey his voice, for the Lord your God is a merciful God." (Deut 4.30-31)
Jesus Himself will lift and take away from Israel the "Veil of Moses", their minds are "softened", their eyes are opened to see and look to "him whom they have pierced' and "mourn for him, as one mourns for an only child, and weep bitterly over him, as one weeps over a first born". (2 Co 3.12-17, Zec 12.10)
And so, "all Israel will be saved; as it is written, 'The Deliverer will come from Zion, he will banish ungodliness from Jacob.' " (Ro 11.26)
