Everyone has an immigrant story at some point in their family...the whole Bible is full of stories of people migrating from one place or other.
Some stand out like the Book of Ruth. Ruth was from Moab.
Jesus was a refugee in Egypt and the Hebrews never forgot their time in Egypt, plus they were exiled and taken captive, and their homeland taken from them.
Dont discount just because someone already believes something else or their culture and langauge is different that they may not be open to Jesus. Gods Love encompasses all humankind and creation. If it did not, and Jesus was not a light to the Gentiles, only Hebrews and the chosen Israelites would believe in God.
