Luke 12:10

Criticism of Jesus was forgivable, but rejection of the Holy Spirit’s testimony that Jesus was the Christ was not (cf. Matthew 12:31-32; Mark 3:28-29). This warning continued the cautions against denying Jesus. Jesus implied that His disciples might face temptations to repudiate faith in Him. To deny Him publicly was bad, but to repudiate one’s faith in Him was worse. Jesus did not mean that God would withhold pardon from the disciple who did this or that he would lose his salvation. He presented the alternative not as a real possibility for disciples necessarily but as a warning that showed the seriousness of that type of denial to discourage apostasy.
