Ephesians 6:16-18

6:16 and in all of this, by taking up the shield of faith with which you can extinguish all the flaming arrows of the evil one. 6:17 And take the helmet of salvation and the sword of the Spirit, which is the word of God. 6:18 With every prayer and petition, pray at all times in the Spirit, and to this end be alert, with all perseverance and requests for all the saints.
