This world is not my home

Leviticus 25:1-28
In the seventh year the land is to have a sabbth of rest, a sabbath to the Lord.
Consecrate the fiftieth year and proclaim liberty throughout the land to all its inhabitants. It shall be a jubilee for you; each one of you is to return to his family property and each to his own clan.
The land must not be sold permanently, because the land is mine and you are but aliens and my tenants. Throughout the country that you hold as a possession, you must provide for the redemption of the land.
This chapter looks forward to the time when the nation will occupy the 'promised land'. The pattern of sevens reflected in the festivals is extended to the land.
One year in seven it is to lie fallow(休耕): a year in which the people, free from much of their ordinary work, are to be taught and trained in God's law.
The fiftieth yrar, following the seventh seven, is an extra fallow year for the land, which reverts to its original owner.
Why?
All of the property are belong to the Lord, I am an alien and tenant before the Lord. This land is belong to the Lord.
Let the land rest is to respect the Lord and give the fruit to the poor and neighbor. And it is good to the land, land has more fertility next year.
All are belong to God so jubilee means to return to the original owner. I have what God gives to me.
How?
Look down everything in this world, this world is not my home.
