God warns us of the reality of the unpardonable sin. If you are not yet a believer, if you have never repented of your sins and believed upon the Lord Jesus Christ, then it is very possible for you to commit this sin, and you need to be warned about it. If, on the other hand, you are a believer, you have repented of your sins and believed upon the Lord Jesus Christ, and there is real evidence that you have experienced the conversion and regeneration of the Holy Spirit, then you can be assured that you have not and will not commit the unpardonable sin.
