The moral glory-the beauty of the ways of God -is what I understand " the riches of His glory" to be. He finds His whole delight in the Son of His love, and you are to bear the stamp of, and to have your heart full of, that Son-seeing the riches of His glory now in the exquisite beauty of a Father with such a Son, and-of His having brought children into such a place.
In "the riches of the glory of his inheritance in the saints." We look forward and see the heavens as they will be in the millennium; see not only one heavenly Man there, but heaven filled with heavenly men; and when the Lord takes possession of the heavens, He has them all as His "staff" around Him. The time is coming when God will use the heavenly saints as His dwelling-place, and possess the heavens.
If I turn my mind to that with which Eph. 3 closes, that is, the breadth and length, and depth and height of love in connection with the infinitude of the divine Being, my mind cannot grasp it; but when I see the central object is Christ -Christ loving me-love presented in a human heart, and He Himself mine; He in the very infinitude of God, able as a Man there to fill me with all the fullness of God, I can lay hold of it; and it is the only way a creature could have to do with the divine infinitude. I am brought by the Father to the Lord Jesus Christ, blessed in Him, -and the love in His heart made to bear on my heart. He has a people down here, and He is filling them with all the divine infinitude, "all the fullness of God." How He has to empty me, to get my heart filled with Himself! Wondrous! to be able to look up there and say, " There is He, my eternal Lover." I cannot grasp the infinitude of God, but I can say, "He does love me." There is peculiar sweetness in being able to say, " Our Lord." He of whom God says, "That is my only-begotten Son;" He, the One in whom dwells all the fullness of the Godhead; and to think that He can love a poor thing like me, and that I can love Him!
A-sheep of the slaughter down here perhaps, but Christ my portion up there; and He saying, " I am the only-begotten Son of the Father; I who have been in His bosom from all eternity, know that Father's heart of love, and the infinite fullness of it, and I want you to have the full idea of the blessedness of believing in my name, because His heart's delight is to fill you up with blessings in me." All the people who believe in Jesus can look up and feel the affections of the Father flowing through the bosom of Christ to them.
