LIFE'S history teaches me one thing. We should treasure our unity because it is through unity that we can accomplish extraordinary things.

It is through unity that the Egyptians were able to build the pyramids. Through unity, the Great Wall of China was built. Through unity, wars have been won. And through unity, the Filipinos were able to liberate themselves from a dictatorial government.

But can the world, with all its people in different races, achieve unity?

Achieving world unity is hard but possible. It's hard because there are barriers and language is one of them. How can we unite when we don't even understand each other?

I remember the story of Babel tower. People in the story had built a tower and when God saw this He realized that men can do anything that they imagined. In Genesis 11 chapters 6 to 8, it says: "Go to, let us go down, and there confound their language, that they may not understand one another's speech. So the Lord scattered them abroad from thence upon the face of all the earth: and they left off to build the city."

Another example is our financial status. There is a big gap between the rich and the poor. Only a few rich people mingle with the poorest of the poor. Why does this happen when we are equal in the eyes of God?

I look forward to the day when people could still work together and unite for one cause despite their differences.

It's good to see people with different religion and race understand and respect each other - Russians and Americans, Muslims and Christians, North and South Korea, black and white Americans, poor and rich together as one.

This is a challenge for all of us. It's not like putting these differences way past beside us but let us try to be one with all these differences.

The world may be divided literally by islands, religion, culture, race and language but the fact remains that we live under one roof - the Earth. And we are here to protect the Earth because a destruction of one part can be a destruction of the whole.

Let unity reign. Though hard, it is still possible.
