'Insulting' in the Bible

And they were saying many other [evil and slanderous] things against Him, blaspheming [speaking sacrilegiously and abusively about] Him.

even though I was formerly a blasphemer [of our Lord] and a persecutor [of His church] and a shameful and outrageous and violent aggressor [toward believers]. Yet I was shown mercy because I acted out of ignorance in unbelief.

How much greater punishment do you think he will deserve who has rejected and trampled under foot the Son of God, and has considered unclean and common the blood of the covenant that sanctified him, and has insulted the Spirit of grace [who imparts the unmerited favor and blessing of God]?
