I wonder if my Western Christian brethren mostly from progressive countries will still love their country or perhaps the citizenship of their country if it is politically divided, rampant of illegal drugs and crimes, rampant of political corruptions, and most of citizens are undisciplined and venal who vote for crooked politicians after accepting cash gifts during elections.
The technique to be humble is always remember that what you have is not yours but from God (1 Cor. 4:7) and always believe that your brother is better than you (Philippians 4:3) The reward for humility is riches, honor and life in Proverbs 22:4 (including eternal life as mentioned in Matthew 5:3)
I love my country because it is blessed with abundant natural resources, beautiful beaches for recreation and good foods but I will never be proud being a citizen of my country because most of my compatriots are ungodly people who don't follow evens simple road laws and willing to vote for corrupt politicians after accepting their bribes. no wonder why God will never permit my country to experience economic progress.
