Question in the Bible

Hebrews 10:29 of how much worse punishment, think ye, shall he be judged worthy

who has trodden under foot the Son of God, and esteemed the blood of the covenant, whereby he has been sanctified, common, and has insulted the Spirit of grace?

Answer in the Bible

Hebrews 6:4-6 For it is impossible to renew again to repentance those once enlightened, and who have tasted of the heavenly gift, and have been made partakers of the Holy Spirit, 

and have tasted the good word of God, and the works of power of the age to come, 

and have fallen away, crucifying for themselves as they do the Son of God, and making a show of him.

Hebrews 6:9-10 But we are persuaded concerning you, beloved, better things, and connected with salvation, even if we speak thus. 

For God is not unrighteous to forget your work, and the love which ye have shewn to his name, having ministered to the saints, and still ministering. 

Matthew 12:31-32 For this reason I say unto you, Every sin and injurious speaking shall be forgiven to men, but speaking injuriously of the Spirit shall not be forgiven to men. 

And whosoever shall have spoken a word against the Son of man, it shall be forgiven him; but whosoever shall speak against the Holy Spirit, it shall not be forgiven him, neither in this age nor in the coming one. 

Mark 3:28-30 Verily I say unto you, that all sins shall be forgiven to the sons of men, and all the injurious speeches with which they may speak injuriously; 

but whosoever shall speak injuriously against the Holy Spirit, to eternity has no forgiveness; but lies under the guilt of an everlasting sin; 

— because they said, He has an unclean spirit.
