Thats a good thorough explanation.

When Jesus talked about the unforgivable sin, he was talking to people who were saying he was doing miracles by the power of satan.

That was the unforgivable sin, attributed jesus miracles to the devil instead of God The Holy Spirit.

Blaspheming the Holy SPirit.

There are a lot of theologians think it is not possible to commit that sin today because Jesus is not on earth doing miracles.

Im going to do a story on this.
