Chaimbn:
Whatever your point about tefillah, yearning for the geulah, etc., the first line in your post is offensive:
“I see no reason why Hashem should give us back the ??? ?????.”
I see lots of reasons why we do indeed need Hashem to redeem us all BB”A.
For starters, so many in Klal Yisrael are suffering, each with their own nisayon from Hashem, regardless of where and how successful they may be.
As well, despite the wonder gift of Shabbos and, liHavdil, the various levels of materialistic success with which He blesses people, it can’t compare to being redeemed with the coming of MAshiach, living in a rebuilt Yerushalayim, with the Torah, avoda in the rebuilt Beis haMikdash, etc. as Chazal has informed us.
Wishing all of Klal Yisrael a Chag kasher viSameach.
