I have been discussing this with many different folks, and getting different answers, as well as some saying that the many different answers apply to blaspheme the Holy Spirit. From suicide to giving satan credit for the miracles of Jesus, to using the H.S.'s name in vain. I personally see it as simply "turning away" from salvation, ergo not having the want or need to be saved, thus condemning one to being "forever lost". But if one has been saved, and realizes the penalty is death, why would one blaspheme in the first place? And with one being "once saved, always saved", where does the unpardonable sin enter? I realize this has probably been beaten to death here, but I was hoping for some input.
