Jesus should’ve returned already.

Jesus promised to return within the lifetimes of those listening to him. This Apocalyptic message (Apocalypticism claims that the end times are very close) is found in the three synoptic gospels. It takes a passage in Isaiah 13 that predicts calamity for Babylon—that the sun and moon will darken and the stars will fall—and repurposes it as a prediction of the end. It also predicts:

[All people on earth will] see the Son of Man coming on the clouds of heaven, with power and great glory . And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds. (Matthew 24:30–31)

The prediction ends saying that this will all happen soon.

This generation will certainly not pass away until all these things have happened (Matthew 24:34).

Let me emphasize those two points: “these things” will happen soon (within months or years, not centuries), and “these things” are obvious and world-destroyingly calamitous. The popular Christian response that this referred to the fall of the Temple won’t fly.

Earlier in the same gospel, we find other references to the imminent coming of the Son of Man:

When you are persecuted in one place [as you spread the gospel], flee to another. Truly I tell you, you will not finish going through the towns of Israel before the Son of Man comes. (Matthew 10:23)

Some who are standing here will not taste death before they see the Son of Man coming in his kingdom (Matthew 16:28).

It’s been a lot longer than one generation. Jesus made a mistake.
