It has been said by many that if you preach the gospel, people will beat a path to your door to hear you. I don't think that is necessarily so. Big crowds are not necessarily a measure of whether the gospel is being preached. Paul surely preached the gospel more effectively than most, and he did not always attract big crowds. Often it was the opposite, working mostly with small groups. While Jesus had his share of multitudes, he also had large numbers who turned away from him when they learned what discipleship was all about.
