Here’s a snippet of what the Bible says about trying to reform yourself by practicing self-denial.
If with Christ you died to the elemental spirits of the world, why, as if you were still alive in the world, do you submit to regulations- "Do not handle, Do not taste, Do not touch" (referring to things that all perish as they are used)-according to human precepts and teachings? These have indeed an appearance of wisdom in promoting self-made religion and asceticism and severity to the body, but they are of no value in stopping the indulgence of the flesh. (Colossians 2:20-23, ESV)
These verses speak plainly about man’s ability to reform himself. It doesn’t matter what label these efforts wear - Buddhism, moralism, or legalism, the result is the same. Aceticism looks good—it looks like holiness—but it doesn’t deal with the root issue, the sinful desires which come from the heart. Only God can do that.
Yes, I mentioned Tiger Woods. But whether I’m talking about him, myself, or anyone else, it doesn’t really matter. Human efforts to reform ourselves fall short of perfection, and perfection is not just a goal, it is the standard of righteousness required for entrance into heaven.
Brit Hume got it right - Tiger Woods needs Christianity. So does everyone else.
