Dynamic Faith by John Hagee

But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.

If prophecy contains predictions that do not come true, the prophecy was false!
If we stoned false prophets in America we wouldn’t have so many people walking around saying, ”Yeah, yeah, thus saith the Lord,” When you presumed to speak as a prophet in Israel and the did not come to pass, they killed you.  That’s one way to reduce the volume of false prophecy.
Deuteronomy 18:21-22—And if you say in your heart, “How shall we know the word which the LORD has not spoken?”  When a prophet speaks in the name of the LORD, if the thing does not happen or come to pass that is the thing which the LORD has not spoken; the prophet has spoken it presumptuously; you shall not be afraid of him.

Simply stated, if someone prophesies in the name of the Lord and it does not come to pass, he or she is not a prophet.  You are ordered not to fear that person.  They do not represent God the Father.

Paul says that we are to prophesy according to the measure of our faith, “Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith’ Romans 12:6.

Dynamic faith will produce a dynamic prophecy saturated with power and anointing.

Limited faith will produce a limited prophecy.
