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.
The life of prayer is a journey with God as well as toward God, a journey in which prayer becomes for those who pursue it as natural as breathing. The first big step is to cease talking TO God and start listening FOR God. And that requires silence. Silence is the language God speaks, and everything else is a translation. "As long as you know you are praying, you are not praying properly", says Benedictine monk David Steindl-Rast. When everything we do is prayer, the fruit is an increase in love, patience and compassion for others, leaving behind the unmistakable taste of holiness.
