Luke 12:8-12 From Fear To Confession.
Jesus just taught the disciples the importance of fearing God, and not fearing men. Some believers have had to actually face death for their faith (v. 4). For some, the only escape would be to deny the Lord (vv. 8-9). In this situation it must have been a great comfort to know that as God cares for sparrows, and is aware of every hair on their heads, that He would give them the words to speak when the challenge came (vv. 6-7, 11). The title ‘Son of Man’ carried eschatological significance, like Daniel’s vision of the throne room of heaven (7:13). Therefore, it is not surprising that Jesus would say that all who denied Him on earth, would be “denied before the angels of God” (v. 9 Cf. II Tim. 2:12). But all those who confess Jesus before men, Jesus will confess them before these same angels (v. 8 Cf. Rom. 10:9). As Matthew pointed out, it is also a confession before the Father (10:32-33 Cf. I Jn. 2:23). Furthermore, Mark describes a person’s denial of Christ as being ashamed of Him (8:38).
Couched within these solemn words are more concerning the Holy Spirit. Those who speak a word against the Son of Man may be forgiven, but those who blaspheme against the Holy Spirit will not be forgiven (v. 10). In Matthew and Mark, this truth follows upon the opinion of some, that He casted out demons by the power of Satan, when it was through the ministry of the Holy Spirit (Cf. Mt. 12:31-32; Mk. 3:28-30). As Jesus said, it is only through the Holy Spirit that one can make a good confession. To speak against the Spirit is to deny oneself the only means of receiving forgiveness. “Such deliberate rejection of the One (the Holy Spirit) who can bring a person to repentance and faith, such sin makes forgiveness impossible” (NGSB, p. 1629). It would be the Holy Spirit, the Helper who would give the saints the words to say at the time of testing (v. 12 Cf. Mt. 10:19-20; Mk. 13:11; Jn. 14:26). Therefore, to deny Christ was to speak against the testimony of the Holy Spirit. Clearly there is no neutrality in one’s confession.
