Andrew Mack, Pastor at Berlin International Community Church, was speaking on Premier's News Hour after German police stated they believed a bomb caused a car to explode.
Police say it was not related to terrorism.
The driver was killed when the vehicle blew up as he was making his way through the western district of Charlottenburg.
Nobody else was injured.
Andrew Mack, speaking in Berlin, told Premier's News Hour people were concerned it had been a terror attack: "Well, I think a lot of people here are thinking about terrorism a lot, especially with the refugee crisis that is happening and so many people moving to Germany - and Europe in general - it's definitely something that's on people's minds over here - but everyone is quite relieved it's not terror related."
He continued: "I think people can pray for the churches, that they can really rise up and really be the light in the city."
The explosion occurred at about 8am-German time on a busy street leading into the heart of the German capital.
Photos from the scene showed the wreckage of a Berlin-registered silver Volkswagen Passat estate, its windows blown out and its front end smashed in, about a kilometre (half a mile) from the capital's landmark Victory Column.
Carsten Mueller, deputy chief spokesperson for Berlin police, said: "(The) explosion occurred inside or on the vehicle.
"Our investigators are working on the assumption that it was an explosive device that caused this."
Police are looking at the possibility that the explosion might be linked to organised crime in the city.
