Jesus wasn't loaned to us. He was given to us forever. He is still what he called himself so many times, "The Son of Man," yet he sits on the throne with his father. They have united with their created beings. What did Jesus give up to become a man? What did God the Father give up when he gave his only son? We don't know now, but perhaps someday.
"For to us a child is born,
to us a son is given,
and the government will be on his shoulders.
And he will be called
Wonderful Counselor, Mighty God,
Everlasting Father, Prince of Peace.
Of the greatness of his government and peace
there will be no end.
He will reign on David’s throne
and over his kingdom,
establishing and upholding it
with justice and righteousness
from that time on and forever.
The zeal of the Lord Almighty
will accomplish this."
"All right then, the Lord himself will give you the sign. Look! The virgin will conceive a child! She will give birth to a son and will call him Immanuel (which means 'God is with us')."
"For God loved the world so much that he gave his one and only Son, so that everyone who believes in him will not perish but have eternal life." John 3:16
