Thanks to Billiam for pointing me to something I've been meaning to study up on for a long time.
"I tell you the truth, all the sins and blasphemies of men will be forgiven them. But whoever blasphemes against the Holy Spirit will never be forgiven; he is guilty of an eternal sin." He said this because they were saying, "He has an evil spirit."
I'll admit, the "unpardonable sin" is a topic that I haven't studied much. While I'm rather uneducated on the topic, here is what I do think;
1. First of all, I'm not real clear on what exactly this "sin" is.
2. Given the context of verse 29, Jesus seems to be saying that the blaspheme he is refering to is attributing acts of Jesus to Satan. Or saying that it is the spirit of Satan preforming these miracles.
3. I don't beleive a Christian could commit this "unpardonable sin." John 5:24 states, "I tell you the truth, whoever hears my word and believes him who sent me has eternal life and will not be condemned; he has crossed over from death to life." If a christian, (one who has beleived and received eternal life,) were to commit this sin, he would have to lose that eternal life, thus making Jesus a liar.
4. It seems logical to me that if an unbeleiver were to commit this "unpardonable sin," the only way that he could never be forgiven for it, (in keeping with God's forgiving character,) would be if his heart were hardened enough that he would never actually seek said forgivness. You decide for yourself whether God hardens his heart or he hardens it himself.
Those are my initial thoughts on the topic. I am going to do some more studying and praying so I can piece together my theoligy on the matter. Thanks again Billiam!
