I personally don't believe the sin of blasphemy against the Holy Spirit is unrepented sin. I believe it is turning from Christ, after once having tasted the power of the Spirit. Turning back to law, self righteousness for our salvation.
Jud 1:3 Beloved! though I was using all diligence to be writing unto you concerning our common salvation, yet have I had necessity to write at once unto you, exhorting you to be earnestly contending for, the faith, once for all delivered unto the saints.
Jud 1:4 For there have crept in unobserved certain men, who, from of old, have been publicly notified for this sentence, ungodly, men, the favour of our God, turning into wantonness, and, our only Master and Lord, Jesus Christ, denying.

Jud 1:12 These are they—who, in your love-feasts, are hidden rocks, as they fare sumptuously together, fearlessly, themselves, shepherding,—clouds without water, by winds swept along, trees autumnal, fruitless, twice dead, uprooted,
Twice dead, there's something to meditate on. To me, twice dead is: dead once prior to the spirit being given, then tasted LIFE through the Spirit, then not staying faithful to the end, turning back to old covenant/administration of death=TWICE DEAD.
Unbelief after first having belief is to be twice dead, (interesting twice dead, and in Revelation "second death")
Jud 1:13 Wild waves of sea, foaming out their own infamies, wandering stars, for whom the gloom of darkness age-abiding hath been reserved.

Heb 10:27 But some fearful reception of judgment and fiery jealousy, about to devour the opposers.
Heb 10:29 Of how much sorer punishment, suppose ye, shall he be accounted worthy, who hath trampled underfoot the Son of God, and, the blood of the covenant, hath esteemed, a profane thing, by which he had been made holy, and, unto the Spirit of favour, hath offered wanton insult?
Heb 10:31 A fearful thing it is to fall into the hands of a Living God!
Heb 10:38 But, my righteous one, by faith, shall live, and, if he draw back, my soul delighteth not in him.
Heb 10:39 We, however, are not of a drawing back unto destruction, but, of faith, unto an acquisition of life.
1Jo 5:1 Whosoever believeth that, Jesus, is the Christ, of God, hath been born: and, whosoever loveth him that begat, loveth him that hath been begotten of him.
1Jo 5:4 Because, whatsoever hath been born of God, overcometh the world; and, this, is the victory that hath overcome the world—our faith.
Heb 6:4 For it is impossible—as to these who have been, once for all, illuminated, who have tasted also of the heavenly free-gift, and have been made, partners, in a Holy Spirit,
Heb 6:5 And have tasted God’s utterance to be, sweet, mighty works also of a coming age,
Heb 6:6 And who have fallen away, again, to be remoulding them into repentance; seeing they are again crucifying unto themselves the Son of God, and holding him up as an example.
Heb 6:7 For, land, which hath drunk in, the rain, thereupon ofttimes coming, and which bringeth forth vegetation fit for them for whom it is even cultivated, partaketh of a blessing from God;
Heb 6:8 But, should it be bringing forth thorns and briars, it is disapproved, and, unto cursing, nigh,—whose end is for burning.
Mat 24:13 But he that shall endure (stay faithful to the Spirit) unto the end, the same shall be saved.
would love to hear you all thoughts.
