Prophetic words from God often foretell what is to come and or share God's heart and thoughts on a matter. This portion of scripture also reveals that prophetic words are also part of the New Testament experience and the word translated "warfare" is very revealing if you look at the Greek word actually translated warfare. It's the Greek word strateia. It's the origin of the word we use for strategy today. Strongs Concordance says that it means "apostolic career, military service or warfare."
It's the same word used in 2 Corinthians 10:3-4, "For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ."
This portion of scripture reveals that our warfare is a spiritual war against strongholds of thought. Every proud that exalts itself against the knowledge of God. Bottom line it is a war for truth against lies.
Looking back at Paul's admonition to Timothy we can understand that God can use prophecy to forewarn us and even give us insight or strategy for the spiritual war that is to come for individuals or in the book of Isaiah's case, for nations.
The Dream Fore-warned Us How the Devil Would Use White Supremacists
The Lord gave Rick Joyner a dream in 1993. It is recorded in "The Coming Catastrophe." The reason I highlight this man's prophetic dream is because he's shared it in other books and articles and at one point around 2011 I remember going to the website of a "Right-Wing Watch" group. They were mocking him and his prophetic word about a coming spiritual civil war and race riots.
When Ferguson occurred a couple of years ago I went back to check and found that group had removed the mocking article. I'd like to share portions of Rick's dream and some other people's prophetic words and share some of the strategy God gave His Church to pray.
