And should you ask yourselves, “How can we know that the oracle was not spoken by the Lord?”—if the prophet speaks in the name of the Lord and the oracle does not come true, that oracle was not spoken by the Lord; the prophet has uttered it presumptuously: do not stand in dread of him.
(NIV Matthew 10:23) When you are persecuted in one place, flee to another. I tell you the truth, you will not finish going through the cities of Israel before the Son of Man comes.
(NIV Matthew 16:27-28) For the Son of Man is going to come in his Father’s glory with his angels, and then he will reward each person according to what he has done. I tell you the truth, some who are standing here will not taste death before they see the Son of Man coming in his kingdom.
(NIV Matthew 24:34) I tell you the truth, this generation will certainly not pass away until all these things [the end times] have happened.
Deuteronomy 18:20-22
