1. National language is the soul of a nation
Beside a flag, a currency, what made a country become a nation is its national language. Make a comparison, a nation has its flesh made of economy, its mind made of politics, and then its soul made of language. Indeed, national language is what represents the national identity of a country.
2. National language is the means of brotherhood and unity
Like the Indonesians said, “Bhinneka Tunggal Ika” - “Unity in Diversity”! National language binds the people together and gives them a sense of being the sons and daughters of the same motherland. It unites the lands and the people into one.
3. Inside a country, people need their own national language to communicate and to co-ordinate
People in the same country, especially in vast country both of land and cultural and ethnic diversity, need a common language so that they can understand each others in daily as well as official communication.
4. National language is the medium of instruction and education
People is the core of a nation. Like parents, a nation needs its national language to instruct and to educate the people so that they can grow up and know their own motherland.
5. Around the world, differences and misunderstandings always make the conflicts come to be, but through a united language, people can come closer and have a sense of harmony.
There’ll be no conflicts anymore if people could communicate and come to an understanding. That is what a national language made for: it gives people a means to express themselves to each others.
6. National language gives a nation the power to grow strong
A nation like a vessel run by human power which will go forward steadily and strongly only and only if the people could work together as one. So, like God said, "They are one people and have one language, and nothing will be withholden from them which they purpose to do." (Genesis 11:5-8)
7. Last but not least, with a national language we can say “Hello” and “Welcome”
What make we know they’re Vietnamese if they didn’t say “xin chào”!? And what make we eagerly travel to Hawaii if they said “welcome” instead of “aloha”!? National language identifies us and makes us proud to be a citizen of a country as we speak it!
