Tradition says that John the beloved went into heaven, and no wonder because love is above the worldly things. As one of the righteous saints said, we are born with a desire to be with God and we will not be at rest except in Him. It is Love. Man is a living being nourished by a mystical food, and this food is love. Give man all the world and deprive him from love, he will die.
Man is like an eagle.
If we put him in a cage and give him a lamb to eat, he will not eat it, but will die instead. For eagles do not live by meat alone, but by flying high and spreading out their wings in the sky. Man lives by love. He seeks and desires to be loved. For man, love is the meaning of life.
