We do not need a "concealed weapons permit" to carry and use the weapons the Lord has provided us with. Indeed -  we need to carry them quite publicly,  in the spirit realm, yes, openly carry them for all to see - devil, angel or man, whatever spirit we encounter needs to see we're packin'! And don't be shy about using them too. When you see the enemy attacking you or someone you love - waste em'! Don't hesitate and for God's sake don't let them talk to you. Fallen spirits will try to negotiate, beg, plead, curse, threaten - anything to keep you from doing what Jesus did to them - that is, cast them out of flesh and away from flesh. Let's reclaim territory for God. And once we've conquered new territor for Him -  let's hold that ground. Don't give it up again- no matter how hard the enemy tries to take it back. He knows anytime he attacks you he's on a suicide mission - he's just hoping you don't know it. You have no idea how powerful you really are  - or do you? God knows it, the devil knows it, but sadly, many of God's people do not know it. They stay on their side of the valley, not daring to confront Goliath. So start carrying your weapons with you openly, everywhere you go and start using them, soldier!
