While Sweden's prime minister assured families of the victims on Monday that they were not alone, Matilda Hector, a Christian journalist in the Scandinavian country told Premier churches have been praying for the safety of the nation and the victims' families during Sunday church services.
She said tens of thousands of people also gathered at the site of the attack Sunday afternoon to pay their respects.
Hector said: "They had posted on Facebook, 'pray for Stockholm' and there have been a lot of prayers going on. I think people unite when these things happen. I've seen it before.
"People really come together and they're like 'we're standing against this".
Hector said people in Sweden are showing much appreciation to police officers in the country for their rapid response to the attack. She said she went to the site of the attack yesterday and saw people hugging officers, leaving flowers on their cars and showed appreciation for catching the terrorist hours after the attack.
Hector believes it's a miracle the death toll wasn't higher.
She says: "It's just a miracle not more people died because this shopping street. I was walking there two days before. Cars usually don't drive there. So, I would be like turning around thinking 'this car should slow down because I am walking.'"
Stockholm police say the truck attack suspect was an asylum seeker from Uzbekistan who had his application for Swedish residency rejected and was being sought for deportation.
Jan Evensson, of Stockholm police, told a news conference on Sunday that the 39 year old suspect's request was rejected in June 2016 but police could not find him for deportation because he was not at the address he had given.
Jonas Hysing, of Sweden's national police said: "We know he has been sympathetic to extremist organisations".
Police are holding five more people in connection with the deadly attack on Friday and have questioned over 500 others.
Four victims killed in the attack included one person from Britain, one from Belgium and two Swedes.
