Matthew 12:31

“Wherefore I say unto you, etc.] This shows, that what follows is occasioned by what the Pharisees had said, concerning the miracles of Christ; imputing them to diabolical influence and assistance, when they were done by the Spirit of God, of which they themselves were conscious; all manner of sin and blasphemy shall be forgiven unto men: not unto all men, for there are some, who, as they are never truly convinced of sin, and brought to repentance for it, so they never have the remission of it; but to such to whom God of his free grace has promised, and for whom he has provided this blessing, in the covenant of his grace; for whom the blood of Christ was shed, for the remission of their sins;…”

“Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men--The word "blasphemy" properly signifies "detraction," or "slander." In the New Testament it is applied, as it is here, to vituperation directed against God as well as against men; and in this sense it is to be understood as an aggravated form of sin. Well, says our Lord, all sin--whether in its ordinary or its more aggravated forms--shall find forgiveness with God. Accordingly, in Mark (Mar 3:28) the language is still stronger: "All sin shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme." There is no sin whatever, it seems, of which it may be said. "That is not a…”

“In this place, and in Mark 3:28-30, Jesus states the awful nature of the sin of which they had been guilty. That sin was the sin against the Holy Spirit. It consisted in charging him with being in league with the devil, or accusing him of working his miracles, not by the “spirit” or “power” of God, but by the aid of the prince of the devils. It was therefore a direct insult, abuse, or evil speaking against the Holy Spirit - the spirit by which Jesus worked his miracles. That this was what he intended by this sin, at that time, is clear from Mark 3:30, “because they said he had an unclean spirit.” All other sins - all speaking against the Saviour himself - might be remitted. But this sin was…”

“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. Mar 3:28; Luk 12:10. Matthew 12:32”

“12:31 In the face of the Pharisees’ accusations of Satanic influence, Jesus had just argued that he, the Messiah, cast out demons through the power of the Holy Spirit. In this context, blasphemy against the Holy Spirit can only mean attributing the ministry and exorcisms of Jesus to Satan’s power.”
