What Did Jesus Know? And Why Should I Care?

I've had a significant bout of what might be best described as "theology disillusionment" lately (similar to this experience described by Stephen over at Undeception). But a recent post by Internet Monk is relevant to my last post, so I thought I'd comment.

In my last post, I discussed Jesus' (seemingly failed) prediction of his own imminent return, and briefly touched on the suggestion that Jesus may not have known when he would return. At the time I didn't even consider it a possibility, but after some thought have allowed it a spot next to the other possible solutions to the problem.

Anyone raising the question "What did Jesus know, and when?" is bound to receive a thousand different answers, some backed up by proof texts and others more emotionally derived. What is common in this discussion (at least among lay-Christians) is the general attitude that the subject of Jesus' knowledge (or lack of it) is interesting, but unimportant.

I'd like to suggest that the issue is more relevant than most would allow. If Jesus truly did not know when he would return, then the expectation of a future (to us) return of Christ is reasonable. But if Jesus' prediction of his own return is to be regarded as authoritative, then it seems more likely that this prophesy was fulfilled around 70AD during the siege and destruction of Jerusalem (and the temple) by the Roman army.

This, in turn, is relevant because it affects how we view the future. Can we look forward to Jesus returning and fixing all the ills of the world? Or are we responsible for affecting this change ourselves? Do we go out and win as many souls as possible, or do we work to end poverty and oppression? So in the end, the answer to these questions lies, in part, in our answer to the question that is the title of this post.

In my Baptist church, both of the options above are heretical to some degree, so again I ask myself: What did I just step in?
