John 3:31

Is above all - This blessed bridegroom, who has descended from heaven, John 3:13 , is above all, superior to Moses, the prophets, and me.

He that is of the earth - John himself, who was born in the common way of man.

Speaketh of the earth - Cannot speak of heavenly things as Christ can do; and only represents Divine matters by these earthly ordinances; for the spirit and meaning of which, you must all go to the Messiah himself.
