It was against the law of Moses to do work on the Sabbath. The Pharisees believed healing a sick person on the Sabbath was "work," so they said that Jesus did wrong when he healed a person on the Sabbath. (See: [[rc://en/tw/dict/bible/kt/lawofmoses]])
No one knows for sure what actions people perform or what words they say when they commit this sin. However, they probably insult the Holy Spirit and his work. Part of the Holy Spirit's work is to make people understand that they are sinners and that they need to have God forgive them. Therefore, anyone who does not try to stop sinning is probably committing blasphemy against the Spirit. (See: [[rc://en/tw/dict/bible/kt/blasphemy]] and [[rc://en/tw/dict/bible/kt/holyspirit]])
