In the Old Testament the Kings would consult with the prophet before going to battle so as to not come face to face with certain death and defeat. The prophet would seek and hear from God concerning the enemies attack strategy and thus direct the king concerning counter measures and strategy to defeat the enemy.
If you do not have a prophetic voice of God speaking to you then you may be missing the foresight of the enemies strategy and thus loosing battles that God intends you to win. Pastors and ministers of the five fold ministry there are some of you who are taking on battles and loosing. Battles that you were never meant to fight. This is because you have not surrounded yourself with those who can see and hear God concerning the strategy of the enemy. Yes, you must be careful concerning who you let speak and influence you. You should seek to test the spirit of the prophets words with scripture. I suggest however that to run from him, because you don't believe prophets exist today or have fear of a false prophet, is causing you defeat. Strategy is key in battle so I encourage you to seek God concerning His strategy in your life. Understand that not everyone who speaks from a prophetic gift or speaks a prophetic word operates in the calling anointed by God in the five fold ministry, but also understand that the prophet does exist today. The office of a prophet speaks to future things and often speaks on international levels. They speak strategy to nations and regions. They are desperately needed in ministry, in the leading of our nations, in our lives. Don't let fear cause you defeat. Do as scripture says and test the spirit of the word given and if it is found to be of the spirit of God, of the heart of God, then take it and gain victory through the word and in Gods word for you.
