There is nothing like a visit to Kever Yosef to strengthen one's emuna - faith - that Eretz Yisrael belongs to the people of Israel. Kever Yosef is one of the places that even the other nations cannot say to us that we stole the land, as Kever Yosef was bought and paid for at full value.
The visits to holy sites are very emotional - unfortunately, we have lost some of them. We must take lessons from the past that after showing weakness brought us to losing control over important sites that are the root of the existence of the Jewish Nation. I pray that our return to [Kever Yosef] will be complete, and that every Jew will be able to come here to the holy sites and pray freely, and to other sites that we lost as well..
