Sin is abhorrent, and it is rampant. In Not the Way It’s Supposed to Be, Plantinga offers one of the most memorable theological descriptions of sin I have encountered: the vandalism of shalom, the corruption of the way God intended things to be.
That framing gave me better language for understanding why sin touches everything—our relationship with God, with one another, with ourselves, our institutions, and creation itself. Plantinga combines biblical theology, cultural observation, and moral reflection to recover a serious Christian vocabulary for sin without reducing it to a list of bad behaviors.
What I appreciate most is that he does not leave the reader in despair. A biblical diagnosis of sin also gives us hope. The problem has a name, grace has an answer, and in Christ something has already been done about it.
