Message 64: 5

There are those that seek to prophesy in the Lord’s name, and in vain they do speak their own words for they know not his Spirit nor his power, for God speaketh not to blaspheme. Fear them not.

When someone comes and tells you that they have a prophesy from the Lord, the first thing you have to do it check it against the word of God. If it does match the word of God then it is not from God. Also the spirit will help us decide if it is true or not. All true prophesies from God will have the spirit confirm them within our hearts.
