Philippians 1:9 And it is my prayer that your love may abound more and more, with knowledge and all discernment, 10 so that you may approve what is excellent, and so be pure and blameless for the day of Christ, 11 filled with the fruit of righteousness that comes through Jesus Christ, to the glory and praise of God.
Paul prays that the Philippians’ love may more and more abound in knowledge. And he wants their love to abound in knowledge so that they might discern what is best. Their love should be a discerning love. Sometimes we do not think of love and wisdom together. But Paul knows that wise love makes wise lives and that foolish love makes foolish lives. Or as he says here, they must have wise love so that they can have lives marked by moral purity, blamelessness, and righteousness until Christ returns. He wants their relationships with God and with each other to prosper, always maintained with the great final day of Christ in view.
