“And this is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless until the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ — to the glory and praise of God.”
Paul does not desire for them to be knowledgeable and insightful, but rather that their LOVE would be knowledgeable and insightful. Knowledge/wisdom/insight have little value unless they come out of love. I can state facts about poverty in the world and the number of people who are strangers to Jesus, and then i can offer wise solutions for those “problems,” but if it does not flow from a place of love, then it is hollow.
I will not be able to discern what is best and pure and blameless, but rather will look for what is most logical. I will not be transformed myself and filled with the fruit of righteousness, but rather will be filled with the vegetables of pride. And i will not seek the glory and praise of God, but rather the glory and praise of men.
But through love i can learn to consider others better than i consider myself and “look not only to [my] interests, but also to the interests of others.” Phil. 2:4
