If I understand scripture correctly, there is only one unpardonable sin. The sin of unbelief. I can be wrong of course. What say you?
1 Unbelief
2 Grieve the Holy Spirit by not wanting to be holy
3 Tasting and knowing God is good, then leaving His truth
4 Not obeying the gospel (the death, burial, and resurrection)
5 A prodigal son who does not return to the Father before death
6 Those who do not remain faithful till the end
7 Those who use the grace of God as a license to sin
8 The wicked and lazy servant
9 The disobedient
10 Those who leave the Faith to follow false doctrines
