John Calvin on Ephesians 3:13

13. Wherefore I desire. His reason for alluding formerly to his imprisonment is now manifest. It was to prevent them from being discouraged when they heard of his persecution. “The original word ἐκκακεῖν signifies ‘to behave like a coward, and through fear to desert the post of battle.’” — Chandler. O heroic breast, which drew from a prison, and from death itself, comfort to those who were not in danger! He says that, he endured tribulations for the Ephesians, because they tended to promote the edification of all the godly. How powerfully is the faith of the people confirmed, when a pastor does not hesitate to seal his doctrine by the surrender of his life! And accordingly he adds, which is your glory. Such lustre was thrown around his instructions, that all the churches among whom he had labored, had good reason to glory, when they beheld their faith ratified by the best of all pledges.

Ephesians 3:14-19

14. For this cause I bow my knees unto the Father of our Lord Jesus Christ,

14. Hujus rei gratia flecto genua ad Patrem Domini nostri Iesu Christi,

15. Of whom the whole family in heaven and earth is named,

15. Ex quo omnis cognatio in coelis et super terram nominatur,

16. That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;

16. Ut det vobis secundum divitias gloriae suae, potentia roborari per Spiritum suum in hominem interiorem,

17. That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,

17. Ut inhabitet Christus per fidem in cordibus vestris, ut sitis in charitate radicati atque fundati,

18. May be able to comprehend with all saints what is the breadth, and length, and depth, and height;

18. Quo valeatis comprehendere cum omnibus sanctis, quae sit latitudo, et longitudo, et profunditas, et altitudo;

19. And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.

19. Cognoscere, inquam, dilectionem Christi, quae cognitionem exsuperat, ut completi sitis in omnem plenitudinem Dei.
