Here is what he said (if you prefer the video version, it is just below):
"Norwegians are also immigrants from Afghanistan, Pakistan, Poland, Sweden, Somalia and Syria. It is not always easy to say where we come from, to which nationality we belong. Home is where the heart is. That cannot always be placed within country borders.
"Norwegians are girls who love girls, boys who love boys, and boys and girls who love each other.
"Norwegians believe in God, Allah, everything and nothing. Norwegians like Grieg, Kygo, Hellbillies and Kari Bremnes. In other words: you are Norway. We are Norway.
"My biggest hope for Norway is that we will manage to take care of each other, that we can build this country further on trust, solidarity, and generosity."
Norway has in recent years taken in a lot of refugees to the point that the country is overloaded with requests and had to tighten its immigration laws. Unfortunately, the country also faces a rise of far-right politics.
The situation in Norway is a situation in which one can easily identify no matter where we live and I think that's why this speech was able to resonate all around the world.
