Here in time we make holiday because the eternal birth which our loving God bore and bears unceasingly in eternity is now born in time, in human nature. St. Augustine says this birth is always happening. But if it happens not in me, what does it profit me? What matters is that it shall happen in me.
There are no limits on true self-giving. It is not just to those one likes that one makes the offering. This involves a love that issues from the very CENTER of the person's being, directed to the CENTER of the other person's being, a love that gives ALL that the person is in order to foster the other person's life, a love that is offered to EVERYONE, without exception and without condition. The love is not offered to people because they are one's friends; people become "friends" because one loves them.
