15. therefore--resuming Php 3:3. "As many of us then, as are perfect," that is, full grown (no longer "babes") in the Christian life (Php 3:3, "worshipping God in the Spirit, and having no confidence in the flesh"), 1Co 2:6, fully established in things of God. Here, by "perfect," he means one fully fit for running [BENGEL]; knowing and complying with the laws of the course (2Ti 2:5). Though "perfect" in this sense, he was not yet "made perfect" (Greek) in the sense intended in Php 3:12, namely, "crowned with complete victory," and having attained absolute perfection.
      thus minded--having the mind which he had described, Php 3:7-14.
      otherwise minded--having too high an opinion of yourselves as to your attainment of Christian perfection. "He who thinks that he has attained everything, hath nothing" [CHRYSOSTOM]. Probably, too, he refers to those who were tempted to think to attain to perfection by the law (Ga 3:3): who needed the warning (Php 3:3), "Beware of the concision," though on account of their former piety, Paul hopes confidently (as in Ga 5:10) that God will reveal the path of right-mindedness to them. Paul taught externally God "reveals" the truth internally by His Spirit (Mt 11:25; 16:17; 1Co 3:6).
      unto you--who sincerely strive to do God's will (Joh 7:17; Eph 1:17).
