What does John 9:39 mean?
This comment can be confusing when compared to statements such as John 3:17 and John 12:47. In those verses, Jesus states He did not come "to condemn" or "to judge." Here, Jesus states He came "for judgment." The reason for Jesus' earthly ministry was to secure our salvation; this required judgment on and against sin. The result of this ministry, however, is the eventual condemnation of those who reject Him (John 3:36).The reference to those who see versus those who are blind summarizes the entire incident with the blind beggar and the religious critics. Those who admit their need and trust in God are those who will be granted sight. The blind man was given both sight and knowledge by Jesus in response to sincere faith. Those who are arrogant and presume they already know will be hardened by the presence of Jesus. Despite their knowledge (John 5:39–40), they'll allow their own prejudice to blind them (2 Corinthians 4:4), making them incapable of understanding what they don't want to understand anyway (John 7:17).
