John 1:49-51 Nathanael answered and saith unto him, Rabbi, thou art the Son of God; thou art the King of Israel. Jesus answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believe thou? thou shalt see greater things than these. And he saith unto him, Verily, verily, I say unto you, Hereafter you shall see heaven open, and the angels of God ascending and descending upon the Son of man.
The second New Testament prophecy fulfilled in John – thou shall see greater things than these – Nathaniel did see many greater works when he saw all the works of Christ for over three years. John 1:51 is to be fulfilled in the eternal kingdom of Jesus on earth when angels will ascend and descend in a more literal way than now (Matt. 13:41-43; 24:31).
Verily, verily means Surely, surely or Amen, amen. So used for emphasis, and only by Him who is the truth (John 14:6). Always used singly elsewhere: in the Old Testament only 16 times; 30 times in Matthew; 15 times in Mark; and 8 times in Luke and only by Christ.
The Son of man is used 88 times of Christ in the New Testament and once in Daniel 7:13 where it was predicted that He would come as the Son of man. It always has the definite article when used of Christ, but not when used of ordinary men. He, Jesus, is God’s Man to redeem mankind. He is God’s answer to satan to guarantee his defeat and restore man’s original dominion.
