The Land of Israel is the inextricable part of our Blessing, the place Hashem chose to Bless, the location for us to keep the full range of His commandments.
Our well-being, national and personal security, and prosperity are all tied to SERVING HIM IN THIS LAND. Our presence here and service is the flow of 'milk and honey' that Torah speaks of:
Deuteronomy 27:1 Observe the entire commandment that I command you this day. Deuteronomy 27:2. It shall be on the day that you cross the Jordan to the Land that Hashem your G-d gives you, you shall set you great stones and you shall coat them with plaster.
Deuteronomy 27:3 You shall transcribe on them all the words of this Torah, when you cross over so that you may enter the Land that Hashem your G-d gives you, a Land flowing with milk and honey, as Hashem the G-d of your forefathers spoke about you.
When Hashem speaks of the curses that will befall us for failing in our service, He speaks of oppression from foreign hands, suffering in foreign lands:
Deuteronomy 28:65 And among those nations you will not be tranquil, there will be no rest for the sole of your foot. There Hashem will give you a trembling heart, longing of eye, and suffering of soul.
Hashem made it absolutely clear for all to understand: There is no blessing in exile.
Exile in and of itself is a curse. He made it clear that blessing is only in the Land, its in living and in serving Him here. The eyes of many of our people are deceived by a mirage of greater wealth and greater security in diaspora.
May this mirage disappear and may our nation unite in understanding this basic Truth and gather willingly in the Land without hardships forcing them, to serve here together to bring Redemption speedily.
