About the Levites and the Jews...

So lately I've been thinking a lot about what the Jews' original role was supposed to be in the world. And that was to be our gateway to God. The example to us of how we should live, and so we could look on the nation of Israel and say "Wow, I want their God." But they failed in their mission, and now we as Christian's also take up that mantel, that command - and show the world a loving God. And the Levites were to take their position as the leaders and examples for the nation of Israel, they were supposed to be the beacon.
Today, as I was reading the book I'm reading for the month, "The Pursuit of God", Tozer mentioned in passing that while the rest of Israel was given territory and land, the Levites were told "I am your portion and your inheritance." They were told to live on the sustenance that the Lord provided, even when the rest of the land lived the cushy life in their own settled territory.
But isn't this what we are called to do? The Levites to the world, the salt of the earth, we were told to not live the cushy life. We were told not to put our feet up. We were told that we are travelers, sojourners on this earth - awaiting our heavenly home. We're not supposed to fill the drawers in this hotel room. Our belongings, our life, the way we live this life - we need to remember this more often.
Lord, please show me how to remember that your plan, your ways, your path, and everything you want for me is the best thing, and show me how to not start settling in here. I love you, Lord. Be my portion. Be my inheritance.
