Eph 6:12-17
12 This is no afternoon athletic contest that we'll walk away from and forget about in a couple of hours. This is for keeps, a life-or-death fight to the finish against the Devil and all his angels.
13 Be prepared. You're up against far more than you can handle on your own. Take all the help you can get, every weapon God has issued, so that when it's all over but the shouting you'll still be on your feet. 14 Truth, righteousness, 15 peace, 16 faith, 17 and salvation are more than words. Learn how to apply them. You'll need them throughout your life. God's Word is an indispensable weapon.
