For those who desire to prophesy... you desire a beautiful thing! in 1 Corinthians 14 we're told that "all" may prophesy.. but this is "not" the same as walking as a prophet (the office). More
A true prophet of God will be terrified when God calls him or her to speak a word of warning or of judgement; they will not have within them anything that "wants to" and will at times run from it (just as Jonah did!). A false prophet will glory in his "words" and will rarely, if ever, speak anything that can be considered "negative". Why? Because "negative words" aren't for the "Day of Grace" of which we're all now in (according to them).
