A three day conference called GC3 (Great Commandment + Great Commission + Great City) will kick off on Thursday evening.
It comes as Metropolitan Police statistics revealed this week that gun and knife crime has risen by a fifth in London.
Rev Chris Green, the vicar of St James Church Muswell Hill where the conference will take place, told Premier News Hour there will be interviews, fellowship, seminars and more.
"We're trying to get a bunch of churches together in north London to pray and worship and praise and challenge one another in terms of what we can do to reach London and help transform our communities for the gospel," he said.
However, he said the work only starts at the conference but must continue afterwards.
Rev Green added: "The difference will be when churches decide to make a difference themselves. We're getting together to pray, to challenge one another.
"It's not to a conference that you look. It's to an individual church which is deciding week by week, day by day, to love the neighbours in their area."
