Ephesians 6:11

When the enemy shall come in like a flood, the Spirit of the Lord shall lift up a standard against him.—Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. Then the devil leaveth him, and, behold, angels came and ministered unto him.

Be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.—And have no fellowship with the unfruitful works of darkness, but rather reprove them.—Lest Satan should get an advantage of us: for we are not ignorant of his devices.—Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour; whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.—This is the victory that overcometh the world, even our faith.

Every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.

I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: but I keep under my body, and bring it into subjection lest that by any means, when I have preached to others, I myself should be a castaway.

I fear, lest by any means, as the serpent beguiled Eve through his subtlety, so your minds should be corrupted from the simplicity that is in Christ.

My brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.

Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.

Resist the devil, and he will flee from you.

You should get into the habit of looking for the silver lining of storm clouds. And once you have found it, continue to focus on it rather than the dark gray of the center. Do not yield to discouragement no matter how severely stressed or surrounded by problems you may be.

A discouraged soul is in a helpless state, being neither able to “stand against the devil’s schemes” (Ephesians 6:11) himself nor able to prevail in prayer for others.
