Don't long for "the good old days." This is not wise. (Ecclesiastes 7:10 NLT)

Let say there is a country called Z. Z used to have a glorious past but now is in humbler times. Z is very upset that now the world order is set by country A. All the countries from B to Z have to follow A. Z felt that all the countries ought to follow Z, like those good old days when Z was a glorious country. So Z stir up hatred for A among its citizens and also those who do not live in country Z but are from the same tribe, race or culture as Z.

Should a Christian who is from the tribe, race, culture or country Z follow what the government of Z and hate A?

Do I not hate those who hate you, O LORD? And do I not loathe those who rise up against you? (Psalm 139:21 ESV)

If anyone says, "I love God," and hates his brother, he is a liar; for he who does not love his brother whom he has seen cannot love God whom he has not seen. (1 John 4:20 ESV)
