1 Corinthians 4:6-7

Now I have applied these things [that is, the analogies about factions] to myself and Apollos for your benefit, believers, so that you may learn from us not to go beyond what is written [in Scripture], so that none of you will become arrogant and boast in favor of one [minister or teacher] against the other. For who regards you as superior or what sets you apart as special? What do you have that you did not receive [from another]? And if in fact you received it [from God or someone else], why do you boast as if you had not received it [but had gained it by yourself]?
