Circumcise your hearts, therefore, and do not be stiff-necked any longer. For the Lord your God is God of gods and Lord of lords, the great God, mighty and awesome, who shows no partiality and accepts no bribes. He defends the cause of the fatherless and the widow, and loves the foreigner residing among you, giving them food and clothing. And you are to love those who are foreigners, for you yourselves were foreigners in Egypt.
God loves immigrants because He was once an immigrant in this world. More than that, God is working towards a world without borders, so you must stop spiritualising every verse and start obeying his commands to love immigrants. Stop looking after number one. Join God's ultimate plan to create a world without borders.
