May be able to comprehend with all saints what is the breadth, and length, and depth, and height;
All Commentaries on Ephesians 3:18 Go To Ephesians 3
John Chrysostom
AD 407
Thus is his prayer now again, the very same as when he began. For what were his words in the beginning? That the God of our Lord Jesus Christ, the Father of glory may give unto you a Spirit of wisdom and revelation in the knowledge of Him; having the eyes of your heart enlightened, that you may know what is the hope of His calling, what the riches of the glory of His inheritance in the saints; and what the exceeding greatness of His power to us-ward who believe. And now again he says the same. That ye may be strong to apprehend with all the saints what is the breadth, and length, and height, and depth; i.e., to know perfectly the mystery which has been providentially ordered in our behalf: and the breadth, and length, and height, and depth; that is, too, the immensity of the love of God, and how it extends every where. And he outlines it by the visible dimensions of solid bodies, pointing as it were to a man. He comprehends the upper and under and sides. I have thus spoken indeed, he would say, yet is it not for any words of mine to teach you these things; that must be the work of the Holy Spirit. By His might, says he, is it that you must be strengthened against the trials that await you, and in order to remain unshaken; so that there is no other way to be strengthened but by the Holy Ghost, both on account of trials and carnal reasonings.
But how does Christ dwell in the hearts? Hear what Christ Himself says, I and my Father will come unto him, and make our abode with him. John 14:23 He dwells in those hearts that are faithful, in those that are rooted in His love, those that remain firm and unshaken.
That ye may be thoroughly strong, says he; so that there is great strength needed.
