The Unforgivable Sin

"Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven."
Matthew 12:31

On a very interesting note, my ESV commentary defines this sin: "this sin is committed today only by unbelievers who deliberately and unchangeably reject the ministry of the Holy Spirit in calling them to salvation."

I think what's interesting is that the commentary defines what the sin against the Holy Spirit actually is. That verse always scared the life out of me previously, because I simply didn't know what it meant, and whether or not I was guilty of it.

All very interesting stuff. Obviously the commentary is just one man's perspective on the verse and could well be wrong to some degree. But it does spark a lot of thought. Does the Holy Spirit work in all people everywhere, calling them to Him? Has everyone on earth been ministered to in some way by the Holy Spirit? And everyone who remains unsaved – have they all rejected the work of the Spirit in their lives?

I'm not sure you can definitely back those statements up with scripture (maybe I'm wrong!). But the following verses do hint at it. They state that God desires all people to be saved, and that it can only happen by the Holy Spirit.

"The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance."
2 Peter 3:9

"No one can say, "Jesus is Lord," except by the Holy Spirit."
1 Corinthians 12:3b
