³ He will say to them, ‘Listen to me, all you men of Israel! Do not be afraid as you go out to fight your enemies today! Do not lose heart or panic or tremble before them.

⁶ So we can say with confidence,

¹² Fight the good fight for the true faith. Hold tightly to the eternal life to which God has called you, which you have declared so well before many witnesses.

Psalm 27

A psalm of David.

¹⁰ Each one of you will put to flight a thousand of the enemy, for the Lord your God fights for you, just as he has promised.

¹² So take a new grip with your tired hands and strengthen your weak knees. ¹³ Mark out a straight path for your feet so that those who are weak and lame will not fall but become strong.

¹¹ Put on all of God’s armor so that you will be able to stand firm against all strategies of the devil. ¹² For we^[a] are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places.

¹³ Therefore, put on every piece of God’s armor so you will be able to resist the enemy in the time of evil. Then after the battle you will still be standing firm. ¹⁴ Stand your ground, putting on the belt of truth and the body armor of God’s righteousness. ¹⁵ For shoes, put on the peace that comes from the Good News so that you will be fully prepared.^{[b] 16} In addition to all of these, hold up the shield of faith to stop the fiery arrows of the devil.^{[c] 17} Put on salvation as your helmet, and take the sword of the Spirit, which is the word of God.

¹⁸ Pray in the Spirit at all times and on every occasion. Stay alert and be persistent in your prayers for all believers everywhere.^[d]
