The people of God is actually a people of peoples, individuals from every tribe and language on this earth who become one people by their union to Jesus. It means Jews and Gentiles. It means Greeks and barbarians. It means anyone, regardless of his or her ethnicity, social status, or past; we’re talking about a people consisting of anyone and everyone who trusts in Jesus and finds in him the significance and happiness we all crave.
