Philippians 3:15

The apostle, having proposed himself as an example, urges the Philippians to follow it. Let the same mind be in us which was in blessed Paul. We see here how he was minded; let us be like-minded, and set our hearts upon Christ and heaven, as he did. 1. He shows that this was the thing wherein all good Christians were agreed, to make Christ all in all, and set their hearts upon another world. This is that whereto we have all attained. However good Christians may differ in their sentiments about other things, this is what they are agreed in, that Christ is a Christian's all, that to win Christ and to be found in him involve our happiness both here and hereafter. And therefore let us walk by the same rule, and mind the same thing. Having made Christ our all, to us to live must be Christ. Let us agree to press towards the mark, and make heaven our end. 2.

therefore--resuming Phi 3:3. "As many of us then, as are perfect," that is, full grown (no longer "babes") in the Christian life (Phi 3:3, "worshipping God in the Spirit, and having no confidence in the flesh"), Co1 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 (Ti2 2:5). Though "perfect" in this sense, he was not yet "made perfect" (Greek) in the sense intended in Phi 3:12, namely, "crowned with complete victory," and having attained absolute perfection. thus minded--having the mind which he had described, Phi 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 (Gal 3:3): who needed the warning (Phi 3:3), "Beware of the concision," though on account of their former piety, Paul hopes confidently (as in Gal 5:10) that God will reveal the path of right-mindedness to them. Paul taught externally God "reveals" the truth internally by His Spirit (Mat 11:25; Mat 16:17; Co1 3:6). unto you--who sincerely strive to do God's will (Joh 7:17; Eph 1:17).
