He said to him, "Most assuredly, I tell you, hereafter you will see heaven opened, and the angels of God ascending and descending on the Son of Man."
This metaphor will receive considerable light when compared with 2 Corinthians 5:19-20: God was in Christ reconciling the world unto himself:- We are ambassadors for Christ, as though God did beseech you by us, we pray you in Christ's stead to be reconciled to God. The whole concerns of human salvation shall be carried on, from henceforth, through the Son of man; and an incessant intercourse be established between heaven and earth. Some have illustrated this passage by the account of Jacob's vision, Genesis 28:12. But though that vision may intimate that God had established at that time a communication between heaven and earth, through the medium of angels, yet it does not appear that our Lord's saying here has any reference to it; but that it should be understood as stated above.
