1. The Apostle Paul starts 2 Cor 10 with the following verses:
2. 2Cor 10:3-6 For though we walk in the flesh, we do not war after the flesh: (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ; And having in a readiness to revenge all disobedience, when your obedience is fulfilled. 
3. STRONG HOLD (like a Fortress), made up of 3 things: A LIE, FEAR & an IDOL. Identify & Repent of them, and the stronghold will break
4. AS We do have WEAPONS – but not after the Flesh..!!! i.e. Not Physical things…
5. Meaning ➔ Don’t try to use physical ammunition, or weapons like guns or knives, or your fists etc..their strength and reach are limited!
6. Isa 54:17 No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their RIGHTEOUSNESS is of Me, saith the LORD. 
7. NOW: The real struggle comes in when someone walking in the flesh alone, are using Physical weapons and ammunition, and all you have is your FAITH, nothing else…!!
8. That can make you feel very inadequate and insecure, and even make you look very “foolish” to yourself as well as your enemy…!!
9. Like David - when he went out to meet Goliath… 1SAM 17, where King Saul wanted David to wear his Armor, but it was way too big for David, and way too uncomfortable: David would not have made it against Goliath, if he even dared going out against him in that armor… BUT Instead: David took it all off, and he stepped out in FAITH – trusting in God – and met Goliath only in his normal clothes he always wore while watching over his sheep, with only his staff, his slingshot & 5 river stones in his pouch
10. 1Sam 17:37 David said moreover, The LORD that delivered me out of the paw of the lion, and out of the paw of the bear, he will deliver me out of the hand of this Philistine. And Saul said unto David, Go, and the LORD be with thee. 
11. 1Sam 17:40 And he took his staff in his hand, and chose himself five smooth stones out of the brook, and put them in a shepherd's bag which he had, even in a scrip; and his sling was in his hand: and he drew near to the Philistine.
12. 1Sam 17:43 And the Philistine said unto David, Am I a dog, that thou comest to me with staves? And the Philistine cursed David by his gods. 
13. 1Sam 17:45 Then said David to the Philistine, Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of the LORD of hosts, the God of the armies of Israel, whom thou hast defied. 
14. And this is where David understood FAITH and TRUST in GOD over fear, and the power of carnal weapons over Spirit, and that FAITH in the Spirit of God, & that the NAME OF GOD is STRONGER and more Powerful than any physical weapons, size or strength could ever be
15. It is like quoting Ps 91 or Praying the Our Father Prayer – through absolute FAITH and TRUST in God – that it carries a Strength and a HOPE, etc… and through your FAITH you WILL SEE The RESULTS turn in your favour through your FAITH being put into ACTION..!!
16. But quoting/praying them like a rhyme or a poem, and you are standing in total fear, doubt and unbelief before this “mighty army in front of you”, then quoting or praying those scriptures will mean absolutely nothing, and you will feel weak, and the chances are you will die and loose your life right there…!!!
17. For by just quoting the scriptures only without faith, there is no power in them…– they aren’t magic words, like Abbra Gadabra, or Simsalabim…etc..    NO!!! You have to add your FAITH with it, to see the POWER in it..!!!
