The hope of our calling

"That the God of our Lord Jesus Christ, the Father of glory, may give you a spirit of wisdom and revelation resulting in knowledge of him.
May the eyes of [your] hearts be enlightened, that you may know what is the hope that belongs to his call, what are the riches of glory in his inheritance among the holy ones."  (Ephesians 1: 17 - 18)

Matthew Henry comments on the subject of Paul's prayer for the Ephesians:
"Now what is it that Paul prays for in behalf of the Ephesians? Not that they might be freed from persecution; nor that they might possess the riches, honors, or pleasures of the world; but the great thing he prays for is the illumination of their understandings, and that their knowledge might increase and abound: he means it of a practical and experimental knowledge. The graces and comforts of the Spirit are communicated to the soul by the enlightening of the understanding. In this way he gains and keeps possession. Satan takes a contrary way: he gets possession by the senses and passions, Christ by the understanding." (Matthew Henry Commentary)
