What does John 3:34 mean?
Dozens of times in this gospel alone, John claims that Jesus has been sent from God. This is the reason the book was written (John 20:30–31), and Jesus' miracles are the primary evidence (John 5:36). Nicodemus recognizes Jesus' miraculous abilities as proof that He is sent by God (John 3:2). Jesus offers other reasons to believe, including the testimony of John the Baptist, and the information found in the Hebrew Scriptures (John 5:36–39). Since Jesus is the only valid source of knowledge about God (John 3:12–13), rejecting Christ means rejecting God (1 John 5:10).In the Old Testament, certain people were given the Spirit of God for a limited time. These include certain prophets (2 Chronicles 24:20; Micah 3:8; 2 Samuel 23:2), various people (Numbers 24:2; 1 Samuel 19:20), and some of the judges (Judges 3:10; 6:34), including Samson (Judges 13—16). Jesus, however, has the Spirit of God continuously. This is why He is said to have the Spirit "without measure," or "without limit."
