Now these things, brethren, I have figuratively transferred to myself and Apollos for your sakes, that you may learn in us not to think beyond what is written, that none of you may be puffed up on behalf of one against the other. 7 For who makes you differ from another? And what do you have that you did not receive? Now if you did indeed receive it, why do you boast as if you had not received it? — 1 Corinthians 4:6, 7.
Neither Paul, nor Apollos, (nor anyone else) should puff themselves up in pride. Anything that a Christian has is a result of God’s gracious and generous favor, and something received from Him, not the result of self-achievement or self-effort. [The Bible Panorama.]
