“The Father loveth the Son, and hath given all things into his hand.”
King James Version (KJV)
3:33 Hath set to his seal - It was customary among the Jews for the witness to set his seal to the testimony he had given. That God is true - Whose words the Messiah speaks.
3:34 God giveth not him the Spirit by measure - As he did to the prophets, but immeasurably. Hence he speaketh the words of God in the most perfect manner.
3:36 He that believeth on the Son hath everlasting life - He hath it already. For he loves God. And love is the essence of heaven. He that obeyeth not - A consequence of not believing.
