John Piper routinely gets directly to the heart of what particular passages mean, all the while keeping it’s meaning in it’s proper context. His interpretation of what exactly Christ says it is that will and will not be forgiven in Matthew ch. 12 is no exception. Most people who misunderstand this passage and think they may have committed this sin usually look over the door Christ himself throws wide open for forgiveness. He writes:
“Why do I hesitate to equate what the scribes said with unforgivable blasphemy? I hesitate because Jesus invites me to with verse 28. “Truly I say to you, all sins will be forgiven the sons of men, and whatever blasphemies they utter.” Literally: “All things will be forgiven to the sons of men, the sins and the blasphemies whatever they blaspheme.” No exceptions are mentioned. The key to understanding the unforgivable sin is how verse 28 can be stated so absolutely (“all sins and blasphemies will be forgiven”) and yet verse 29 can say that there is a blasphemy and a sin beyond forgiveness. ” -Piper
