Because in His divinity, He is everywhere, He does not ascend nor descend. Therefore, in the Liturgy of St. Gregory we say “And You ascended into the heavens in the body…” This ascension is evidence that His Glorified Body is not subject to the earth’s gravitational laws. It is also evidence of His Divinity. He ascended before His disciples as they were looking. This scene strengthened their faith because the Lord not only resurrected using His Divine power, but He also ascended into heaven in Fathernt of them.
In His ascension to Heaven, He did not leave His church alone on Earth.
