The Preferred One, Verse 30
Jesus is preferred by God the Father in many ways. God has given him a name that is above every name (Phil. 2:9). He has made him better than the angels (Heb. 1:4), greater than the temple (Matt. 12:6), greater than Solomon (Matt. 12:42), greater than Jacob (John 4:12), a greater witness than John (John 5:36), the greater One who is in us (1 John 4:4), and was before Abraham (John 8:58).
The Unknown One Vs. 31
No one knows Jesus until he is revealed by God the Father. John knew him as a man, but he did not know Jesus as the Son of God until the Father revealed Jesus to him. Notice Luke 10:22 All things are delivered to me of my Father: and no man knoweth who the Son is, but the Father; and who the Father is, but the Son, and he to whom the Son will reveal him.
The Revealed One, Vs. 32-34
John saw the Spirit of God as a dove, and God the Father through the Spirit of God revealed Jesus to John so that John could reveal him to the masses.
Jesus was first revealed as the one who "baptizeth with the Holy Ghost," which took place on the Day of Pentecost in a mighty way to accredit and empower the Lord's churches.
Jesus was also revealed to John as the "Son of God." Later Jesus would reveal himself in the synagogue in his own city that he was the "anointed" one (Luke 4:18). The shocker to the hearers is recorded in Luke 4:21 And he began to say unto them, This day is this scripture fulfilled in your ears.
Now the final result of this revelation was that some would have Jesus do the same miracles in his own city that he had done at Capernaum; but Jesus said that a prophet is without honor in his own country. Then the hate came from those in Nazareth, as revealed in Luke 4:28 And all they in the synagogue, when they heard these things, were filled with wrath,
So, some in our day, after hearing the Gospel of Jesus Christ, will desire miracles from him; some will believe; some will hate the message and the man, as they did in the days of John the Baptist.
