Quoting from the Book of Deuteronomy, Chapter 10, verses 16 to 19: “Circumcise your hearts, therefore, and do not be stiff-necked any longer. 17 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.18 He defends the cause of the fatherless and the widow, and loves the foreigner residing among you, giving them food and clothing. 19 And you are to love those who are foreigners, for you yourselves were foreigners in Egypt.”
You might be tempted to reply that this only applied to the Israelites, as it was spoken to them by God, through Moses, but may I remind you that God, as revealed in the Scriptures and through Jesus Christ “…is the same yesterday, today and forever.” (Hebrews 13:8) and “Heaven and earth will pass away, but My words will never pass away.” (Matthew 24:35)
