Street preaching is very effective

Jesus said to go into the world to reach sinners, not the other way around. Sinners won't come to Church, so let's go into the city and tell them about Jesus Christ! 

"And he said unto them, Go ye into all the world, and preach the gospel to every creature." Mark 16:15 

"How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?" Romans 10:14
