Jesus was wrong?

I was looking for something about my marriage and I came across this article, The Best Christian Argument for Marriage Equality is that the Bible Got It Wrong. That title is pretty provocative, but I'm used to that now, so it wasn't a big deal. The tagline got me though: Christians need to accept that Jesus was sometimes wrong—in fact, he might even want us to. Say what?

I don't have time to go through the argument right now, but at some point, Pete Enns was invoked. His writings, and his podcast with Jared Byas, have had a pretty profound impact on me recently. But then as I was skimming the article, I am across a scripture reference: Matthew 24:34. I froze. I think I had blocked it out. Could this be THAT reference? Could it be anything but?

The article had a link to Bible Gateway, and a KJV reference at that. Here it is:

Verily I say unto you, This generation shall not pass, till all these things be fulfilled.

I can't remember if it was in Korea or Maryland, I think Korea, that I wrestled with this verse. And now I can't remember what conclusion I came to. But whatever I thought then, when I look at it now, there's only one thing that comes to mind: Jesus was wrong. Damn.
