Mark 3:28-29 AMP
“I assure you and most solemnly say to you, all sins will be forgiven the sons of men, and all the abusive and blasphemous things they say; but whoever blasphemes against the Holy Spirit and His power [by attributing the miracles done by Me to Satan] never has forgiveness, but is guilty of an everlasting sin [a sin which is unforgivable in this present age as well as in the age to come]”— [Matt 12:32; Luke 12:10]
