I did a Google search for Bible passages that deal with forgiveness.  I have always had a problem with forgiving people.  I can get to the point where I understand their actions.  I don’t dwell on the past.  However actual forgiveness is something I have a hard time with.

I found the following verses which I need help in understanding:

Luke 12: 8-10

8“I tell you, whoever acknowledges me before men, the Son of Man will also acknowledge him before the angels of God. 9But he who disowns me before men will be disowned before the angels of God. 10And everyone who speaks a word against the Son of Man will be forgiven, but anyone who blasphemes against the Holy Spirit will not be forgiven.

A person who speaks against “the Son of God”, Jesus, will (can?) be forgiven. That is clear. 

“anyone who blasphemes against the Holy Spirit will not be forgiven”. 

What is the difference between speaking against Jesus and blaspheming(?) against the Holy Spirit?  

I was my understanding that if a person was truly repentant God would forgive them of anything.
