Numbers 16:41 But on the morrow all the congregation of the children of Israel murmured against Moses and against Aaron, saying, Ye have killed the people of the Lord.
[Patriarchs & Prophets pp 405] It was this act that sealed their doom. They had committed the sin against the Holy Spirit, a sin by which man's heart is effectually hardened against the influence of divine grace. “Whosoever speaketh a word against the Son of man,” said Christ, “it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him.” Matthew 12:32. These words were spoken by our Savior when the gracious works which He had performed through the power of God were attributed by the Jews to Beelzebub.
It is through the agency of the Holy Spirit that God communicates with man; and those who deliberately reject this agency as satanic, have cut off the channel of communication between the soul and Heaven. God works by the manifestation of His Spirit to reprove and convict the sinner; and if the Spirit's work is finally rejected, there is no more that God can do for the soul. The last resource of divine mercy has been employed.
The transgressor has cut himself off from God, and sin has no remedy to cure itself. There is no reserved power by which God can work to convict and convert the sinner. “Let him alone” (Hosea 4:17) is the divine command. Then “there remaineth no more sacrifice for sins, but a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.” Hebrews 10:26, 27.
Ephesians 4:29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. 30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
May The Lord add His blessing to the study of His word. God bless!
