Jesus makes no promise that in the blink of an eye we will suddenly become totally different people who have vastly different tastes, attitudes, and perspectives. Paul makes it very clear that we will have our true selves revealed and that once the sins and habits and bigotry and pride and petty jealousies are prohibited and removed, for some there simply won’t be much left. “As one escaping through the flames” is how he put it.
It’s very common to hear talk about heaven framed in terms of who “gets in” or how to “get in.” What we find Jesus teaching, over and over and over again, is that he’s interested in our hearts being transformed, so that we can actually handle heaven. To portray heaven as bliss, peace, and endless joy is a beautiful picture, but it raises the question: How many of us could handle it, as we are today? How would we each do in a reality that had no capacity for cynicism or slander or worry or pride?
