As a Palestinian teenager, Mosab Hassan Yousef decided to follow Jesus after a British businessman gave him a Bible in the marketplace.

Yousef is the son of one of the founders of the terrorist group Hamas.

At age 17, he says, he couldn’t understand how he was serving Allah by killing innocent civilians — particularly other Muslims. He asked questions, but got no answers.

Until the traveling businessman handed him a Bible, that is.

Secretly the teen began reading it. And it changed his life. He continued to work alongside his father, Sheik Hassan Yousef, in the West Bank city of al- Ghaniya near Ramallah. However, he dared not tell anybody that he had quietly, privately embraced the Christian faith and had begun working for Israeli intelligence.

He offered to work from within Hamas as an informant, tipping off the Israelis when bombings or assassinations were being planned.

Yousef said that while some may want to “scare people about Islam” for personal profit, he is speaking out as “a person who loves my people.”

“I cannot wait for them to be liberated,” he said of his fellow Palestinians and Muslims worldwide. “When I see the example of liberty and freedom in this country, I want this to go to my people.”

What changed his life?

One stranger who cared enough to hand him a Bible.

And God did the rest.
