[CynicalBear]

If you have faith and believe, you have the Holy Spirit within you. Scripture tells us of many who were saved and indwelt with the Holy Spirit immediately. It is that which inspires the good works. If you have the Holy Spirit within you it is indicative of having been saved because the Holy Spirit would not indwell an unsaved person. No one with the indwelt Holy Spirit would be able to sin without feeling the guilt. If you blaspheme the Holy Spirit He leaves you and will not come back. Thus the deadly sin of blaspheming the Holy Spirit.

True; but Christians do sin and experience guilt. They even fall off the faith completely, as you yourself indicated in you preceding post.
