Having your favourite teacher is not only silly but wrong

^6-7 I have used myself and Apollos above as an illustration, so that you might learn from what I have said about us not to assess man above his value in God’s sight, and may thus avoid the friction that comes from exalting one teacher against another. For who makes you different from somebody else, and what have you got that was not given to you? And if anything has been given to you, why boast of it as if it were something you had achieved yourself?
