Q: Blasphemy of the Holy Spirit
There are a lot of believers who come across this passage of Scripture and get really scared worrying they'll commit it. Usually someone concerned about this is a believer and that already shows [your heart 😇] that you do not want to commit it.
Here are some resources to help. Go through all of them for a clear overall understanding. Some are sermons which my pastor calls Bible studies... because they are. [Reputable] Pastors spend 40 hours or so a week studying under the Holy Spirit and in the Word to bring a message to us.
Hope this helps 😊
