Unlike many other nationalist hymns, this text keeps our focus on God. This is a Go who created the universe, who leads and governs his people, who serves as our protector, and who refreshes his people with divine love. Presumably the text referred originally to white Anglo-Saxons, but in its present form it is fitting for all citizens and residents of any country. Christians too may sing this anthem, using it to recognize the national association we have on earth but remembering that the practice of "true religion" (st. 3) transcends earthly loyalties and promotes citizenship in the kingdom of heaven.
