It is important to note that there is a huge difference between a false prophet and a prophet who makes a mistake. Do not assume because one makes a mistake that he or she is a false prophet. A person starting out or one who is nervous could make a mistake so do not crucify a person for a simple mistakes.
The Scripture give clear references to a false prophet they are not just someone who makes a mistake they come with the intention to deliberately mislead you so it is important that you test the spirit.
It is important that we weigh the word that has being brought to us instead of just blatantly rejecting it out of hand else we end up rejecting prophesy take it to God, test the spirit and remember prophesy itself is futuristic in nature and could take the life time of the prophet to come to past.
