He who comes from above is above all. He who is from the Earth belongs to the Earth, and speaks of the Earth. He who comes from heaven is above all.

 John goes on: we can believe what Jesus says, because on him God poured out the Spirit in full measure, keeping nothing back. Even the Jews themselves said that the prophets received from God a certain measure of the Spirit. The full measure of the Spirit was reserved for God's own chosen one. Now, in Hebrew thought the Spirit of God had two functions--first, the Spirit revealed God's truth to men; and, second, the Spirit enabled men to recognize and understand that truth when it came to them. So to say that the Spirit was on Jesus in the completest possible way is to say that he perfectly knew and perfectly understood the truth of God. To put that in another way--to listen to Jesus is to listen to the very voice of God.
