This Sunday's reading from Ephesians 6:10-20 is all about being heavily armored to combat cosmic evil powers,
Finally, be strong in the Lord and in the strength of his power. Put on the whole armour of God, so that you may be able to stand against the wiles of the devil. For our struggle is not against enemies of blood and flesh, but against the rulers, against the authorities, against the cosmic powers of this present darkness, against the spiritual forces of evil in the heavenly places. Therefore take up the whole armour of God, so that you may be able to withstand on that evil day, and having done everything, to stand firm. Stand therefore, and fasten the belt of truth around your waist, and put on the breastplate of righteousness. As shoes for your feet put on whatever will make you ready to proclaim the gospel of peace. With all of these, take the shield of faith, with which you will be able to quench all the flaming arrows of the evil one. Take the helmet of salvation, and the sword of the Spirit, which is the word of God.
Pray in the Spirit at all times in every prayer and supplication. To that end keep alert and always persevere in supplication for all the saints. Pray also for me, so that when I speak, a message may be given to me to make known with boldness the mystery of the gospel, for which I am an ambassador in chains. Pray that I may declare it boldly, as I must speak.
The first Anglican Bishop of Liverpool, J.C. Ryle (1816 – 1900), takes the ball and runs with it,
"Go on, then, to your journey’s end, “rejoicing in hope of the glory of God.” (Rom. 5:2) Go on, rejoicing in the thought that though you are a poor sinner Jesus is a most gracious Saviour, and that though you have trials here for a little season, heaven shall soon make amends for all.
Go on, wearing hope as a helmet in all the battles of life,—a hope of pardon, a hope of perseverance, a hope of acquittal in the judgment day, a hope of final glory.
Put on the breast-plate of righteousness: take the shield of faith; have your loins girt about with truth: wield valiantly the sword of the Spirit. But never forget—as ever you would be a happy Christian—never forget to put on the “helmet of hope.” (1 Thess. 5:8)
Go on, in spite of an ill-natured world, and be not moved by its laughter or its persecution, its slanders or its sneers. Comfort your heart with the thought that the time is short, the good things yet to come, the night far spent, the “morning without clouds” at hand. (2 Sam. 23:4) When the wicked man dies his expectation perishes; but your expectation shall not deceive you,—your reward is sure.
Go on, and be not cast down because you are troubled by doubts and fears. You are yet in the body: this world is not your rest. The devil hates you because you have escaped from him, and he will do all he can to rob you of peace.
The very fact that you have fears is an evidence that you feel you have something to lose. The true Christian may ever be discerned by his warfare quite as much as by his peace, and by his fears quite as much as by his hopes.
Go on, and “hope to the end for the grace that is to be brought to you at the revelation of Jesus Christ.” (1 Pet. 1:13) Yet a little time, and faith shall be changed to sight, and hope to certainty: you shall see even as you have been seen, and know even as you have been known.
A few more tossings to and fro on the waves of this troublesome world,—a few more battles and conflicts with our spiritual enemy,—a few more years of tears and partings, of working and suffering, of crosses and cares, of disappointments and vexations,—and then, then we shall be at home.
The harbour lights are already in view: the haven of rest is not far off. There we shall find all that we have hoped for, and find that it was a million times better than our hopes.
There we shall find all the saints,—and no sin, no cares of this world, no money, no sickness, no death, no devil. There, above all, we shall find Jesus, and be ever with the Lord! (1 Thess. 4:17)
Let us hope on. It is worth while to carry the cross and follow Christ. Let the world laugh and mock, if it will; it is worth while to have “a good hope through grace,” and be a thorough decided Christian.
I say again,—Let us hope on."

Without Faith, there can be no Hope.
Where Jesus is, there is Hope.
