Question:
Does Hebrews 10:26-31 mean that if we have a knowledge of the truth and backslide, there is no forgiveness?
Answer:
No, it does not. Some of the strongest pleas in the whole Word are made to backsliders. Read Jeremiah 2 and 3; 2 Peter 3:9; John 6:37; Psalms 147:11; Ezekiel 33:11. Read the whole of Hosea, in which God pleads again and again with backsliding Ephraim. The conditions presented in Hebrews 10:26-31 show not simply a backsliding but an utter turning away from God’s only means of reaching souls—His Spirit-filled Word and the Lord Jesus Christ.
There is hope for the backslider. “Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of his heritage? he retaineth not his anger for ever, because he delighteth in mercy. He will turn again, he will have compassion upon us; he will subdue our iniquities; and thou wilt cast all their sins into the depths of the sea.” Micah 7:18, 19. The passage in Hebrews 10 refers to the hopelessness of those who utterly reject the divine and only means of helping.
