The first victim to be formally identified was Mohammed Alhajali, a 23-year-old Syrian refugee, who came to Britain in 2014 with his brother.
One of the family's daughters said the community had been "very nice" and the family were getting help.
"We miss him terribly, and are pulling together as a family and trying to stay strong under these tragic circumstances". We know that there are still bodies of those who died inside the building and we want to return those people to their families as soon as we possibly can.
Mr Cundy said the death toll - which increased from 58 - could still change as investigations continue, but not as significantly as it has previously.
He also added that he intends to release videos and images of the scene inside Grenfell Tower tomorrow, but stressed that he would not do that until all families affected had been contacted.
Speaking as he left the church with his wife Saadiya, Khan said: "I've spent time with the local community, not just the Christian congregation, but members of all faiths here at the church, grieving, sharing their stories".
"The search operation will be painstaking and having been in there myself it's really hard to describe the devastation that the fire has caused".
They were reported missing by Catherine Lindsay - who was teaching them English - but the family has now been found.
London police on Saturday raised to 58 the number of deaths either confirmed or presumed following the horrific inferno that turned the city's Grenfell Tower public housing block into a charred hulk. She said Britain remains "resolute in the face of adversity" after the horrendous fire and recent extremist attacks in London and Manchester. "My understanding is the cladding in question, this flammable cladding which is banned in Europe and the USA, is also banned here", Chancellor of the Exchequer Philip Hammond said in a recent interview with BBC's The Andrew Marr Show.
She said volunteers were unable to get hold of any money, despite huge donations of cash being made and Theresa May pledging £5 million in emergency funds.
The investigation into the fire will span a "wide range of areas", Cundy said, from its original construction, to the refurbishment and how it has been managed and maintained. "This has not happened with these funds", they said.
"But we will do it with our utmost professionalism and we will do everything we can as quickly as we can to locate everybody who is in there".
