Korah would not have taken the course he did had he known that all the directions and reproofs communicated to Israel were from God. But he might have known this. God had given overwhelming evidence that He was leading Israel. But Korah and his companions rejected light until they became so blinded that the most striking manifestations of His power were not sufficient to convince them; they attributed them all to human or satanic agency . The same thing was done by the people, who the day after the destruction of Korah and his company came to Moses and Aaron, saying, “Ye have killed the people of the Lord.” Notwithstanding they had had the most convincing evidence of God's displeasure at their course, in the destruction of the men who had deceived them, they dared to attribute His judgments to Satan, declaring that through the power of the evil one, Moses and Aaron had caused the death of good and holy men. 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 Saviour 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 . {PP 404-5}
