Nathanael said to him, "How do you know me?" Jesus answered him, "Before Philip called you, when you were under the fig tree, I saw you."
      b. Yet they are great things which he here foretels: You shall see heaven opened, and the angels of God ascending and descending upon the Son of man. (a.) Some understand it literally, as pointing at some particular event. Either, [a.] There was some vision of Christ's glory, in which this was exactly fulfilled, which Nathanael was an eye-witness of, as Peter, and James, and John were of his transfiguration. There were many things which Christ did, and those in the presence of his disciples, which were not written (John 20:30; John 20:30), and why not this? Or, [b.] It was fulfilled in the many ministrations of the angels to our Lord Jesus, especially that at his ascension, when heaven was opened to receive him, and the angels ascended and descended, to attend him and to do him honour, and this in the sight of the disciples. Christ's ascension was the great proof of his mission, and much confirmed the faith of his disciples, John 6:62; John 6:62. Or, [c.] It may refer to Christ's second coming, to judge the world, when the heavens shall be open, and every eye shall see him, and the angels of God shall ascend and descend about him, as attendants on him, every one employed; and a busy day it will be. See 2 Thessalonians 1:10. (b.) Others take it figuratively, as speaking of a state or series of things to commence from henceforth; and so we may understand it, [a.] Of Christ's miracles. Nathanael believed, because Christ, as the prophets of old, could tell him things secret; but what is this? Christ is now beginning a dispensation of miracles, much more great and strange than this, as if heaven were opened; and such a power shall be exerted by the Son of man as if the angels, which excel in strength, were continually attending his orders. Immediately after this, Christ began to work miracles, John 2:11; John 2:11. Or, [b.] Of his mediation, and that blessed intercourse which he hath settled between heaven and earth, which his disciples should be degrees be let into the mystery of. First, By Christ, as Mediator, they shall see heaven opened, that we may enter into the holiest by his blood (Hebrews 10:19; Hebrews 10:20); heaven opened, that by faith we may look in, and at length may go in; may now behold the glory of the Lord, and hereafter enter into the joy of our Lord. And, Secondly, They shall see angels ascending and descending upon the Son of man. Through Christ we have communion with and benefit by the holy angels, and things in heaven and things on earth are reconciled and gathered together. Christ is to us as Jacob's ladder (Genesis 28:12), by whom angels continually ascend and descend for the good of the saints.
