"Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of Man" (John 1:51).

In this statement to Nathaniel, Jesus is saying that a greater revelation will come to Nathaniel. He will realize that it is through Jesus Christ that God reaches to man on earth and through Jesus Christ that man has access to God in Heaven.

By this figurative language Christ represented his meditorial work. "He spanned and bridged the gulf that separated man from his maker. Nathaniel and other disciples, by the miracles, wonders, and work of Christ, were able to see the glory of Christ as mediator, just as if they saw heaven opened, and a shining way stretching up to it from his cross, on which angels were passing in rejoicing throngs."
