Philippians 1:9

9. This I pray The prayer (Philippians 1:9-11) is for their continual increase in love to Christ, his cause, and his people; that love which underlay their fellowship with the gospel, the subject of the thanksgiving, and also made them willing partakers with himself in suffering. Yet not in the love alone did he desire growth, but more in certain adjuncts which are always necessary to its best direction and most useful employment. Love may be very pure, honest, and full, and at the same time impulsive, misdirected, injudicious, and even injurious. So he prays for its increase in knowledge a full knowledge of the truths of the gospel, by which they would readily detect any perversion of, or addition to, them.

And in judgment Doubtless the moral judgment, or spiritual insight.
