“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 blamesless for the day of Christ …”

Phil 1:9-10

Here is an excellent and challenging comment on these verses from Alec Motyer:

“the hymn-writer caught the matter perfectly:

That I may love what Thou dost love,

And do what Thou wouldst do.

In this respect Christian love is no different from any other sort of love: it can both waste itself upon unworthy objects and also bestow itself on proper objects in unworthy ways. In other words it needs divine illuminative knowledge in order to know what to love, and discernment to know how to love.”
