God becomes Man! - The Greatest Day of All Time

Some wisdom from  Archimandrite Justin Popovich:

God is born on earth, and moreover He is born as a man: perfect God and perfect man--the unique God-man. And He has forever remained as the God-man both on earth and in heaven. Indeed, the God-man is the first perfect man on earth. Perfect man? Yes, because only in the God-man is man without sin, without evil, without death, totally filled with God, and thereby with all divine perfections.

Jesus came to earth as the God-man to show us the way of life God has determined for us to be united with Him eternally.  Our aim must be to become like Him is all respects and unite with Him. 

Man is only a true man when he is completely united with God, and in everything and every way completely lives in God, thinks in God, feels in God, acts in God, is virtuous in God, is immortal in God, is eternal in God. Only and solely in God is man a man, a true man, a perfect man, a man in whom all the fullness of the Godhead lives. 

The life of man?--Only and solely as the Divine Life in the God-man does our life become and forever remain sinless, immortal, God-like, holy, perfect, eternal.

Everything that man is, and everything that is of man perfectly lives, works, thinks, feels, is human, immortal, divine, and eternal only and solely in the God-man and through the God-man. Only through the God-man Christ is man divine majesty and the highest value next to God in all worlds. For this reason God became man, and has remained the God-man for all eternity. With the God-man Christ, all that is God's has become man's, human, ours, so that each of us individually and all of us assembled together in the Divine-human body of Christ, the Church, might become god-men, having at tained "to the perfect man, to the measure of the stature of the fullness of Christ" (Eph. 4:12-13).

There is no historical event that can compare to this event––God becomes man.

Therefore Christmas, the day of the birth of the God-man, the Lord Jesus Christ, is the greatest and most important day in the history of all the worlds in which man moves and lives. Truly this is "great joy"--truly the only true joy, the only eternal joy of a human being in all worlds.
