“To speak of Christ’s love as ‘surpassing knowledge’ means that it is so great that one can never know it fully. We can never plumb its depths or comprehend its magnitude. No matter how much we know of the love of Christ, how fully we enter into His love for us, there is always more to know and experience.
And the implication, in the light of the following words, is that we cannot be as spiritually mature as we should be unless we are empowered by God to grasp the limitless dimensions of the love of Christ.”
–Peter T. O’Brien, The Letter to the Ephesians, PNTC (Grand Rapids: Eerdmans, 1999), 264.
