Note: Puffed up isn’t a term we use often, but pride is and is deadly in relationships. Love is not puffed up.
“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?” I Corinthians 4:6-7 (NKJV)
Ellicott: (7) “Even if one possesses some gift or power, he has not attained it by his own excellence or power; it is the free gift of God.”
(regarding false teachers)
“So let no one judge you in food or in drink, or regarding a festival or a new moon or Sabbaths, which are a shadow of things to come, but the substance is of Christ. Let no one cheat you of your reward, taking delight in false humility and worship of angels, intruding into those things which he has not seen, vainly puffed up by his fleshly mind, and not holding fast to the Head, from whom all the body, nourished and knit together by joints and ligaments, grows with the increase that is from God.” Colossians 2:16-19
Poole: (18) “We must not, under any pretext of humility, presume to know what belongs to our duty and God’s service better than Christ doth, showing us that he alone is the true and living way, and we may come boldly by him,”
