Despising the spirit of grace/election/foreknowledge.whirlwind said:The unforgiveable sin can only be committed by the elect and only in the end of days....
13:11 But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost.
That "hour" is Satan's hour of temptation. So, to premeditate or to not allow ourselves to be delivered during that time or to speak our own mind would be to committ the unforgiveable sin.
Heb 10:26-29
26 For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a certain terrifying expectation of judgment, and the fury of a fire which will consume the adversaries. 28 Anyone who has set aside the Law of Moses dies without mercy on the testimony of two or three witnesses. 29 How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace? NAS
Grace is the light of God's choice/election. God's purpose is manifested in his electing work. His electing work is out of his foreknowledge. This foreknowledge is God's planned parenthood. It is the Father's plan for the family of Jesus' eternal priesthood.
Heb 2:11-13
11 For both he that sanctifieth and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren,
12 Saying, I will declare thy name unto my brethren, in the midst of the church will I sing praise unto thee.
13 And again, I will put my trust in him. And again, Behold I and the children which God hath given me. KJV
He who blasphemes against Jesus' family of priests, is blaspheming against the body, the temple of the holy Spirit, and there remains no more sacrifice for this sin.
