Paul began to talk to the Corinthian church about how they were acting because some of them were saying they belonged to a certain disciples camps because they were baptized by that disciple. When we become as these Christians had become we are really mature in our walk with God . But if we are not mature we can become like these and say we are of this preacher or that preacher. This also can come from a lack of teaching the whole word of God. Besides when we start choosing who our favorite preachers we are making camps and followings which can become a very dangerous thing because we can be swayed by preachers teachings and not really study out the word of God for ourselves.
