The Apostle prays that they might have all kinds of knowledge and spiritual judgment, so that they might do things just fit to be done-that they might know in what one thing differs from another-that they might be connoisseurs in the Christian path; not only not fall into sin, but have the knowledge of just the right thing to do in the circumstances, for the standard is the satisfying of the heart of Christ, not, Where is the harm? The Apostle desires that they might discern things now as they will be when brought into the light in that day of Christ. It is as if he said, I want you to think of the Lord Jesus, and know what will please the heart of Christ. There is the delight of pleasing Christ, and also the delighting in the thing that pleases Him, by the active energy of the Spirit of God.
