"And I will dwell in the midst of the Children of Israel and I will be their G-d." (From this week's Torah portion, T'ztaveh, Exodus 29:45)
"And I will dwell in the midst of the Children of Israel." The Holy Temple is the necessary tool for the coronation of the Creator as King of the World. A king is not a king without a nation, a land, a capital and a royal palace. The nations of the world coronate kings of flesh and blood, enslave themselves to humans and build them glorious palaces. But the King of Israel is not a mere human. Israel testifies to the Kingdom of G-d. The Holy Temple in Jerusalem is His royal palace.
This is the way to achieve liberty for the Nation of Israel and for the world. One person is not slave to another, but we are all servants of G-d. The first of those servants is the human king of Israel whose entire purpose is to fulfill the destiny of the Nation of Israel: to perfect the world in the Kingdom of Heaven.
