What does John 10:35 mean?
This comment by Jesus is both a crucial reference to the perfection of God's Word and a tactical use of His critics' own methods. Jesus is under threat of immediate stoning, presumably for blasphemy. When goaded to repeat His claims by a mob, Jesus went even further and equated Himself with God (John 10:22–31). Now, Jesus is using a technique familiar to these religious leaders. scribes and Pharisees would often debate Scripture using various rhetorical tactics and convoluted arguments; Jesus is using one of those in this encounter.To counter their claim that Jesus should be considered a blasphemer for saying He is "one" with God, Jesus pointed to Psalm 82. In that passage, God's own Word referred to human beings using the same literal word as used for God Himself: elohim. Other Old Testament passages use the same word in a judicial context (Exodus 21:6; 22:8).
Jesus' point is not that humans are divine, but that those who are divinely enabled to perform the will of God are, in a poetic form, referred to as "gods" in Scripture. As this retort continues, Jesus will point out that He has been proven by powerful supernatural evidence. This connection has not been lost on everyone; others have come to the same conclusion (John 3:1–2; 10:19–21). His claim to truth is much stronger than that of anyone else. His works—His miracles—should be absolute proof that God sent Him. As such, charges of blasphemy against Jesus in this case fall short.
Jesus also makes a point of rejecting the suggestion that the Word of God can be "broken." By this, Jesus means that the verses He quoted could not be dismissed as an error. They could not be written off as a mistake. This is the doctrine of inerrancy, which says Scripture is perfectly accurate in everything it intends to say. Jesus, in this moment, not only implies inerrancy, but He even grounds His argument in it.
