John 1:49-51
Jesus calls Nathaniel
49 Then Nathaniel declared, "Rabbi, you are the Son of God; you are the King of Israel.
50 Jesus said, "You believe because I told you I saw you under the fig tree. You shall see greater things than that." 51 He then added, "I tell you the truth, you shall see heaven open, and the angels of God ascending and descending on the Son of Man."
Jesus calls Nathaniel...Jesus tells Nathaniel He had seen him under the fig tree...Nathaniel recognizes that Jesus is the Son of God...Jesus tells Nathaniel that he will see heaven open and the angels of God ascending and descending on the Son of Man...
Nathaniel would get to see this ascension...
In Acts 1:9 Jesus is ascended into heaven...The two men who were dressed in white, said to the disciples, Men of Galilee, why do you stand here looking into the sky?...This same Jesus, who was taken into heaven will come back in the same way you have seen Him go into heaven...
