(This is the third excerpt from chapter 17 of my manuscript on the Sermon on the Mount; the first two excerpts are here and here.)
It’s not easy to accept Jesus’ declaration that the pure in heart are blessed, but it’s possible to assent intellectually without letting it interfere with our daily lives. It’s far harder to heed John Owen’s dictum, “Be killing sin or it will be killing you,”[1] and declare war on our sin out of a desire to be pure in heart; but though that’s a major spiritual commitment, it’s still one we usually make with unconscious caveats. We assume there are limits to how far we can be expected to go in order to put sin to death in our lives. We assume God is reasonable—on our terms, by our definition—in his expectations.
Jesus shatters those assumptions, because his demands aren’t reasonable at all. In fact, they’re barbarically unreasonable. He commands us to do whatever we have to do to overcome sin in our lives, no matter how much we expect it to hurt or how much we have to give up. If we try to tell him he’s asking too much of us, he looks us right in the eyes and says, “No, I’m not.” There are no exceptions, no loopholes, no limits, and no statute of limitations to his command.Read more→
