The Temple is still in ruins.
Isaiah 64:1 AS FIRE BURNS MATERIALS THAT MELT, FIRE CAUSES WATER TO BUBBLE, TO MAKE YOUR NAME KNOWN TO YOUR ADVERSARIES; NATIONS WOULD QUAKE FROM BEFORE YOU.
Isaiah continues his message from the last chapter. If only God would show Himself then nobody would doubt or rebel against Him.
Isaiah 64:2 WHEN YOU PERFORMED AWESOME DEEDS FOR WHICH WE DID NOT HOPE; [WHEN] YOU DESCENDED, MOUNTAINS DRIPPED FROM BEFORE YOU.
Isaiah 64:3 AND WHEREOF NO ONE HAD EVER HEARD, HAD EVER PERCEIVED BY EAR, NO EYE HAD EVER SEEN A GOD BESIDES YOU PERFORM FOR HIM WHO HOPED FOR HIM.
Isaiah 64:4 YOU SMOTE HIM WHO REJOICED AND WORKED RIGHTEOUSNESS, THOSE WHO MENTIONED YOU IN YOUR WAYS; BEHOLD, WHEN YOU BECAME WROTH FOR WE HAD SINNED; THROUGH THEM, OF OLD, WE WOULD BE SAVED.
Intepreted as nobody has seen that which God has prepared for the righteous in the Afterlife. Also only they who have learnt the Torah of Israel have ever received a glimpse of the Ultimate Truth.
Isaiah 64:5 AND WE ALL HAVE BECOME LIKE ONE UNCLEAN, AND LIKE A DISCARDED GARMENT ARE ALL OUR RIGHTEOUS DEEDS, AND WE ALL HAVE WITHERED LIKE A LEAF, AND OUR INIQUITIES CARRY US AWAY LIKE THE WIND.
Isaiah 64:6 AND NO ONE CALLS IN YOUR NAME, AROUSES HIMSELF TO CLING TO YOU, WHEN YOU HID YOUR COUNTENANCE FROM US, AND YOU CAUSED US TO WANDER THROUGH OUR INIQUITIES.
Isaiah 64:7 AND NOW, O LORD, YOU ARE OUR FATHER; WE ARE THE CLAY, AND YOU ARE OUR POTTER, AND ALL OF US ARE YOUR HANDIWORK.
This verse tells us that God has hidden His face from us and we are in danger of losing. If however we overcome and “take hold” of God He will save us.
Isaiah 64:8 BE NOT WROTH, O LORD, SO VERY GREATLY, AND REMEMBER NOT INIQUITY FOREVER; PLEASE LOOK, ALL OF US ARE YOUR PEOPLE.
God is our father. He is the potter who forms us according to His will. Every living being is created with the basic constituency most suited to itself as it - itself - would want if it knew the options and task laid upon each option.
Isaiah 64:9 YOUR HOLY CITIES HAVE BECOME A DESERT; ZION HAS BECOME A DESERT, JERUSALEM A DESOLATION.
We have to realize all the time that we are His people and endeavor to act accordingly.
Isaiah 64:10 OUR SANCTUARY AND OUR GLORY, WHEREIN OUR FOREFATHERS PRAISED YOU IS BURNT WITH FIRE, AND ALL OUR COVETED PLACES HAVE BECOME A WASTE.
God wants the cities of Israel and especially Jerusalem to be built up and inhabited with Israelites.
Isaiah 64:11 CONCERNING THESE WILL YOU RESTRAIN YOURSELF; WILL YOU REMAIN SILENT AND AFFLICT US SO VERY GREATLY?
The Temple is still in ruins. Every descendant of Israel is responsible for the Temple and should strive to rebuild it.
[Isaiah 64:12] WILT THOU REFRAIN THYSELF FOR THESE THINGS, O LORD? WILT THOU HOLD THY PEACE, AND AFFLICT US VERY SORE?
Even if we are not aware of it our soul is afflicted as long as the cities of Ancient Israel are not settled by Israelites. The world is not as it should be as long as the Temple is not rebuilt.
