The tribe of Levi did not have a designated region as an inheritance, but the Lord gave them cities throughout the other tribes,
And the Lord spoke to Moses in the plains of Moab by the Jordan across from Jericho, saying: “Command the children of Israel that they give the Levites cities to dwell in from the inheritance of their possession, and you shall also give the Levites common-land around the cities…” (Numbers 35.1–5).
Christians are priests and the Lord has done the same thing for us. No place on Earth exists that the Lord says belongs exclusively to Christians, but we dwell among all the inhabitants of the Earth. We own property, as the Levites did.
We serve God in our respective locations, but we serve God for the sake of the people living around us, otherwise, they would have no one interceding for them.
