I have become a foreigner in a foreign land

Exodux 2:1-23
Moses,saying, “I drew him out of the water."
When Pharaoh heard of this, he tried to kill Moses, but Moses fled from Pharaoh and went to live in Midian, where he sat down by a well.
Moses agreed to stay with the man, who gave his daughter Zipporah to Moses in marriage.  Zipporah gave birth to a son, and Moses named him Gershom,saying, “I have become a foreigner in a foreign land.
Why?
Moses wanted to make righteousness by his strength. It is not the right way to make it.
Moses became foreigner in a foreign land, God used the wildness to transfer Moses to his servent. Get rid of his flesh strength, subdued to the Lord.
All of the Jesus followers are foreigners of this land.
How?
This land is not my home, my home is on the heaven.
