Luke 12:10

And everyone who speaks a word against the Son of Man will be forgiven, but the person who blasphemes against the Holy Spirit ¹  will not be forgiven. ² 

Mt 12:31,32; Mr 3:28,29; Lu 23:34; 1Ti 1:13; Heb 6:4-8; Heb 10:26-31; 1Jo 5:16

¹ sn Blasphemy against the Holy Spirit probably refers to a total rejection of the testimony that the Spirit gives to Jesus and the plan of God. This is not so much a sin of the moment as of one’s entire life, an obstinate rejection of God’s message and testimony. Cf. Matt 12:31-32 and Mark 3:28-30.

² tn Grk “it will not be forgiven the person who blasphemes against the Holy Spirit.”
