_Prayer for Power_. Ephesians 1:15-20, "Wherefore I also, after I heard of your faith in the Lord Jesus, and love unto all the saints, cease not to give thanks for you, making mention of you in my prayers; that the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him: the eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints, and what is the exceeding greatness of his power to usward who believe, according to the working of his mighty power; which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places." The Church at Ephesus was in every way remarkable, but to this people Paul wrote his most spiritual epistle, which in itself is a compliment to them, for as in another instance it was not necessary for him to write unto them as if they were carnal. With this people for the space of two or three years he labored, as we find recorded in Acts the nineteenth chapter and the tenth verse, "And this continued by the space of two years; so that all they which dwelt in Asia heard the word of the Lord Jesus, both Jews and Greeks." Acts 20:31, "Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears." There were no divisions in this church as at Corinth; there were no heresies as at Galatia, and no dissensions as at Philippi; and yet, for all that, he prays most earnestly. The natural question for us to ask is, just what is it for which he prays, and the question is easily answered. First: For advancement in knowledge; he asks God that the eyes of their understanding might be enlightened. Under this general petition there are three special requests. (1) _That they might know the hope of their calling_. We have but to study Paul's Epistles to realize that this calling involved: A perfect vision, for one day it is Christ's promise and teaching that they shall see him as he is. The hope of this would keep them faithful. It involved, in the next place, a perfect likeness, for, seeing him as he is, they would become like him, and the hope of this would keep them clean. It involved, in the third place, a perfect union, for when this hope of their calling is fulfilled there is no possibility of anything coming between the believer and Christ; so the fellowship must be perfect.
