Christians believe the New Testament to be the word of God, however, it contains many false prophecies. So it is obvious this book is not from God. There is much evidence to say the New Testament is tampered with by the Roman Catholic church, so we don’t know if Jesus really ever said these false prophecies. But if Jesus did say these, he is a false prophet.
Jesus promised this in this verse = Mark 13:27-31
26 “At that time people will see the Son of Man coming in clouds with great power and glory. 27 And he will send his angels and gather his elect from the four winds, from the ends of the earth to the ends of the heavens.
28 “Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. 29 Even so, when you see these things happening, you know that it[a] is near, right at the door. 30 Truly I tell you, this generation will certainly not pass away until all these things have happened.
Now obviously, none of this has happened and the people that Jesus was talking to and their generation had died centuries ago! This makes Jesus a false prophet according the Torah.
Deuteronomy 18:20 – 22 But any prophet who presumes to speak in my name an Oracle that I didn not command him to utter, or who speaks in the name of other Gods – that prophet shall die. And you should 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 presumpsouly, do not stand in dread of him”
This verse spoken by God proves Jesus was a false prophet.
