This week Washington Post columnist, Michael Gerson, captured the words of Syrian children stranded in Lebanon: "My home is all broken in Syria," said a little girl. "A rocket came and hit my father in the head," said another. One boy drew a picture of a bomb. 

Someone once said, "It's not the millions that move us, but the one." The crisis in Syria has certainly proven this to be true.

My colleagues in Syria, Jordan. Iraq and Turkey are exhausted from responding to the escalating crisis. But they also express an unequivocal gratitude: the world has finally chosen to embrace the plight of refugee families in what is being called the worst humanitarian crisis since World War II. And we know millions more call themselves refugees, not just Syrians—about 60 million globally. We are living in an age of unprecedented migration of people, a global exodus.  

As I talk with people across the country, I encounter two prevailing emotions. The first is compassion. The image of Aylan, the child who washed up on a beach in Turkey, tipped the world's collective conscious towards empathy. Aylan gave us a glimpse into the pain of those forced to flee their homes. We identify with Aylan's mother or sister or brother or aunt or cousin. For me, I feel the anguish of his father.

Our compassion spills over to families fleeing ISIS in northern Iraq or to the millions fleeing war in places like South Sudan, Congo, or Yemen, to name only a few. People are rising to the biblical call to "welcome the stranger," an indispensable ethic for anyone choosing to follow Jesus of Nazareth who once set out on the refugee trail himself. Churches are coming together, too, to reach out to refugee families in Forth Worth, Seattle, Boise, Durham, Chicago, Los Angeles, Highpoint, Atlanta and so many other cities. And communities take notice when people live out their faith in the public square.

But the second emotion is fear. Fear rises in us when we talk about welcoming Syrians or Iraqis here in the United States. Many are concerned about creating a gateway for terrorism. Their fear is understandable. But a bit of history and data can go along a way to assuage our concerns. The United States has resettled over 3 million refugees since the late 1970's. None have been terrorists. World Relief, the organization I serve, has resettled nearly 250,000 refugees since 1978. None have been terrorists.

There is good reason for this: the vetting process of refugees who qualify for resettlement is extensive. The FBI, State Department, national intelligence agencies, and Department of Homeland Security are all involved in a process that takes upwards of 18-24 months with significant clearance hurdles. Refugees are not the threat that some try to make them out to be.

It turns out that refugees are a good investment too. Most people believe refugees are a burden to the countries that receive them. But the opposite is true. Studies show that welcoming refugees often has a positive effect on a host country's economy and wages. Germany is being talked about at the new "land of the free and the brave" because they are accepting upwards of 800,000 Syrians. While we applaud Germany's moral courage, they are also smart. Their decision is as much economic as moral. 

Our global exodus is also personal. We all have our own stories as immigrants or refugees, whether first generation or several removed. I recently found my wife, Belinda, staring at a photo of her grandfather, Alexis Koshanov, or "Grandpa Alex," as Belinda knew him. Alexis fled Lithuania just before Hitler's whisper campaign, but was turned away at Ellis Island because he was Jewish. He later immigrated into the United States via Canada, but his sister died in Auschwitz and his brother barely survived Dachau. Today's new exodus reminds Belinda of another exodus not long ago: "I am a refugee, just two generations removed," she said, tears filling her eyes.  

Almost everyday I hear about a church, neighborhood, or community opening their arms to a refugee family. These people are heroes. Why?  Because they have chosen to open their hearts, their minds, and even their homes to refugees. As they do, the language of "refugee" quickly fades away to become "brother" or "sister" and eventually "American." "These people are friends," my colleagues say. "As a nation, we can do more."

We are at our best not when we turn our backs or demand our rights or talk about walls but when we welcome the refugee, the sojourner, the immigrant, with Alyan's image engraved on our hearts and Alex's history etched into our memories. We are at our best—as a people, a Church, a community and a nation—not when we fear but when we love.
