In the visions of the night, I was there, watching,
and behold, one like a son of man was coming with the clouds of heaven,
and he approached the Ancient of Days, and they ushered him in before Him.
And dominion was given to him, and majesty, and a kingdom.
And all peoples, nations, and languages shall serve him.
His dominion shall be an eternal dominion that will not pass away,
and his kingdom will not be destroyed.
From Daniel’s Vision in Daniel 7:13–14
In Daniel’s vision, the Son of God is the one to whom the “Ancient of Days” grants an eternal kingdom, and God the Father is the “Ancient of Days”. But don’t let that title fool you. God is indeed “ancient”, but God is not old. If I may say it this way, God has for a very, very long time not been old, and throughout eternity to come, He will keep on not being old.
Age is the shadow of death, and death is the end result of sin. God cannot sin, and so, He cannot die. Therefore, He never ages. And for those who love Him, He has promised the same kind of life He has: eternal, ageless life.
