Evelyn Waugh is the author of such literary classics as A Handful of Dust and Brideshead Revisited. He possessed a scathing wit, and numerous other personal flaws we won’t enumerate here.

After flirting with agnosticism, Waugh converted to Catholicism. Yet he still struggled. One day a woman asked him, “Mr. Waugh, how can you behave as you do and still remain a Christian?” He replied, “Madam, I may be as bad as you say, but believe me, were it not for my religion, I would scarcely be a human being.”

Even for those who possess a genuine belief in Jesus, there’s no guarantee that they won’t behave badly. The classic passage on this internal battle comes from the quill of the apostle Paul himself. “I am all too human,” he wrote, “a slave to sin. . . . I don’t want to do what is wrong, but I do it anyway” (Romans 7:14,19).

He continued: “There is another power within me that is at war with my mind. This power makes me a slave to the sin that is still within me. Oh, what a miserable person I am! Who will free me from this life that is dominated by sin and death?” (vv.23-24). Paul satisfied his own rhetorical question: “Thank God! The answer is in Jesus Christ our Lord” (v.25).

Followers of Christ are transformed in an instant, but they don’t “arrive”—not in this life, anyway. One of Jesus’ closest friends, the disciple John, summed it up this way: “We are already God’s children, but He has not yet shown us what we will be like when Christ appears. But we do know that we will be like Him, for we will see Him as He really is” (1 John 3:2).
