In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one;
16. Taking the shield of faith. Though faith and the word of God are one, yet Paul assigns to them two distinct offices. I call them one, because the word is the object of faith, and cannot be applied to our use but by faith; as faith again is nothing, and can do nothing, without the word.
Here is a general exhortation to constancy in our Christian course, and to encourage in our Christian warfare. Is not our life a warfare? It is so; for we struggle with the common calamities of human life. Is not our religion much more a warfare?
Commenting on Ephesians 6:10-18
Above all, taking the shield of faith,.... Which may be understood either of the grace of faith, which is like a golden shield, precious, solid, and substantial; and like a shield of mighty men, by which mighty things are done, and by which the believer not only repels, but conquers the enemy.
