“¶ Wherefore I say vnto you, All maner of sinne and blasphemie shall be forgiuen vnto men: but the blasphemie against the holy Ghost, shall not bee forgiuen vnto men.”
1611 King James Version (KJV)
12:31 The blasphemy against the Spirit - How much stir has been made about this? How many sermons, yea, volumes, have been written concerning it? And yet there is nothing plainer in all the Bible. It is neither more nor less than the ascribing those miracles to the power of the devil, which Christ wrought by the power of the Holy Ghost. #Mark 3:28|; Luke 12:10.
Mt 12:31 The blasphemy [against] the [Holy] Ghost shall not be forgiven. Compare Mr 3:28 Lu 12:10. Much discussion has arisen concerning the nature of sin against the Holy Spirit, and nothing is plainer. Mr 3:30 explains it. It was ascribing Christ's works to demoniac influence. These works were wrought by the power of the Spirit.
