João 1:51

Verily, verily. — This is the first use of this formula of doubled words, which is not found in the New Testament outside St. John’s Gospel. They are always spoken by our Lord, and connected with some deeper truth, to which they direct attention. They represent, in a reduplicated form, the Hebrew “Amen,” which is common in the Old Testament as an adverb, and twice occurs doubled (Números 5:22; Neemias 8:6). In the Hebraic style of the Apocalypse the word is a proper name of “the faithful and true witness” (Apocalipse 3:14).,

I say unto you... ye shall see. — The earlier words have been addressed to Nathanael. The truth expressed in these holds for all disciples, and is spoken to all who were then present — to Andrew and John and Peter and James (João 1:41) and Philip, as well as to Nathanael.

Hereafter is omitted by several ancient authorities, including the Sinaitic and Vatican MSS., but there is early evidence for the insertion, and as the omission removes a difficulty in the interpretation, it is probably to be traced to this source. If retained, the better rendering is, henceforth, from this time onwards.

Heaven opened. — More exactly, the heaven opened, made and continuing open. The thought was familiar, for Psalmist and Prophet had uttered it to God in the prayers, “Bow Thy heavens, O Lord, and come down” (Salmos 144:5); “O that Thou wouldest rend the heavens, that Thou wouldest come down” (Isaías 64:1). The Presence then before Nathanael was the answer to these longings of the soul.

The angels of God ascending and descending. — Referring again to the history of Jacob (Gênesis 28:12).

The Son of man. — This is probably the first time that this phrase, which became the ordinary title used by our Lord of Himself, fell from His lips; but it meets us more than seventy times in the earlier Gospels, and has been explained in the Note on Mateus 8:20. It will be enough to observe here that it is suggested by, and is in part opposed to and in part the complement of, the titles used by Nathanael. He could clothe the Messianic idea only in Jewish titles, “Son of God,” “King of Israel.” The true expression of the idea was not Hebrew, but human, “the Son of Man,” “the Word made flesh;” the Son, the true representative of the race, the Second Adam, in whom all are made alive; the Son of Man. The word is ἄνθρωπος, not ἀνήρ; homo, not vir. It is man as man; not Jew as holier than Greek; not free-man as nobler than bond-man; not man as distinct from woman: but humanity in all space and time and circumstance; in its weakness as in its strength; in its sorrows as in its joys; in its death as in its life. And here lies the explanation of the whole verse. The ladder from earth to heaven is in the truth “The Word was made flesh.” In that great truth heaven was, and has remained, opened. From that time onwards messengers were ever going backward and forward between humanity and its God. The cry of every erring and helpless child to its Father for guidance and strength; the silent appeal of the wronged and down-trodden to the All-Just Avenger; the fears and hopes of the soul burdened by the unbearable weight of sin, and casting itself on the mercy of the Eternal Love — all these are borne by messengers who always behold the face of God (Mateus 18:10). And every light that falls upon the path, and strength that nerves the moral frame; every comfort to the heart smarting beneath its wrong; every sense of forgiveness, atonement, peace — all these like angels descend that ladder coming from heaven to earth. Ascending precedes descending, as in the vision of old, Heaven’s messengers are ever ready to descend when earth’s will bid them come. The revelation of the fullest truth of God is never wanting to the heart that is open to receive it. The ladder is set up upon the earth, but it reaches to heaven, and the Lord stands above it. It goes down to the very depths of man’s weakness, wretchedness, and sin; and he may lay hold of it, and step by step ascend it. In the Incarnation, Divinity took human form on earth; in the Ascension, Humanity was raised to heaven.
