Will Christians that say they don't have to do nothing because Christ did it all explain what this is talking?

Unfortunately many churches have adopted the "do nothing" doctrine, because it is a very popular thing to be told that you may go to heaven at the snap of a finger. It is a cheap faith invented by ambitious overseers to draw numbers, and presenting Christ as a product. Again, unfortunately, this fable bypes the first thing that Christ tells us we must do, which is repent.
