In the Bible, the Ascension references the ascent of Jesus Christ into heaven forty days after his resurrection. The scriptures referencing the Ascension (in Luke and Acts) tell of a literal ascension which marked an end to the earthly work of Jesus. The New Testament says Jesus will return just as he left — physically through the clouds — but is currently in Heaven at he right hand of God.
LUKE 24: 50-51
50 And he led them out as far as to Bethany, and he lifted up his hands, and blessed them. 51 And it came to pass, while he blessed them, he was parted from them, and carried up into heaven.
