The blasts left one of Borussia Dortmund's players injured and prompted the first-leg of a Champions League quarter-final match against Monaco to be postponed until Wednesday evening.
Pastor Maxwell Aruwa from Living Hope International Church, which is ten minutes away from Borussia Dortmund's stadium, told Premier: "It was shocking but we've been praying..."
"Naturally, people will be more fearful but, on the other side, when you watch the news conference from the police and when you look around, you see that they've really tightened the security."
Heavy security is in place ahead of the rescheduled match, while German police say they are investigating "in all directions" after the blasts.
Pastor Aruwa added: "Today is a little bit quiet in Dortmund. When you drive around [or] walk around, you can see that people are very careful. Many people are avoiding crowded places, so you see that some people are still fearful."
Police are working on the basis the blasts, which struck at 7.15pm as the Borussia Dortmund team bus was leaving the L'Arrivee Hotel and Spa for the stadium, were directed at the players.
Officers are investigating the authenticity of a letter found nearby which claimed responsibility for the incidents.
According to German prosecutors, letters found nearby suggest a possible Islamic extremist motive for the blasts.
Pastor Aruwa went on to say: "Especially now that Germany accepted a lot of refugees in the last year, especially the Germans have been fearful a terrorist attack might occur in Germany, so we've been praying about this."
A spokesman for Angela Merkel condemned the explosions as "a repugnant act".
Pastor Aruwa also said: "I would just request for Christians all over to pray for Dortmund, for Germany and for Europe because this is something that prayer is needed, for there to be peace and security."
