Isaiah 54:17 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.
Remember it said that no weapon formed against thee shall prosper, it never said that the weapon will not form against you. Many times, we see the enemy forming the weapon and we panic. We see the enemy using the weapon against us and we panic. We may even feel the effects of the weapon and we panic. The scripture also said that it shall not prosper, meaning that it's going to failed even when it looks like its prospering. This is a faith confession. It's not enough to just speak it, you have to choose to believe it even when you don't see it or you're not felling it.
