Charles Ellicott Commentary 1 Corinthians 3:21

"Wherefore let no one glory in men. For all things are yours;" — 1 Corinthians 3:21 (ASV)

Therefore. This is not because of what has been previously mentioned, but rather it introduces what the Apostle is about to say. Let party-spirit cease. Do not degrade yourselves by calling yourselves after the names of any man, for everything is yours—so teachers exist only for you.

The Apostle's enthusiasm, as he speaks of the privileges of Christians, leads him beyond the bare assertion necessary for the logical conclusion of his argument. He enlarges on the idea, dwelling in a few brief and impressive utterances on the limitless possessions—in life and in death, in the present life and that which is future—which belong to those who are united with Christ.

But they must remember that all this is theirs because they are Christ’s. They are possessors because they are possessed by Him. “His service is their perfect freedom,” as the Collect in the English Prayer Book puts it, or, more strikingly, as it occurs in the Latin version, “Whom to serve, is to reign.”
