“Therefore, all who are mature, let’s have this attitude; and if in anything you have a different attitude, God will reveal that to you as well” (Philippians 3:15).
Paul’s reference to maturity is a masterful play, having expressed that he has not even yet “grasped it” (v.12) or “taken hold of it” (v.13), and the necessity to “press on” (v.14). In other words, only the immature would ever come to a place of smug satisfaction in the life of faith. These are recognized by their tendency to speak fiercely and brutishly about matters they have not really seen or known. The greatest enemy of spiritual growth is a comfortable satisfaction with what you have experienced and currently understand. Only human arrogance would seek to place such limitations upon God the Creator.
