2 Corinthians 10:3-4 AMP
“For though we walk in the flesh [as mortal men], we are not carrying on our [spiritual] warfare according to the flesh and using the weapons of man.  The weapons of our warfare are not physical [weapons of flesh and blood].

Our weapons are divinely powerful for the destruction of fortresses.” We as Christians face spiritual battles every day. Some battles will make us feel vulnerable, some battles will weaken our defenses. But every battle fought in the name of the Lord, fought with the full armour of God We will win, sometimes in increments because of our weaknesses and others pulling down Jericho size walls because we have given the battle to the Lord and He gives us the strength and might.
