"There is nothing on this earth more to be prized than true friendship."-St. Thomas AquinasSt Thomas Aquinas is on the money on this. In friendship, we have an opportunity to imitate the Divine Love given to us. If we are willing to work for the good of the other, in pursuit of beauty, goodness, and truth, then friendship is awesome. That's what I hope for on this earth.
This is one of the few times I will unashamedly refer you to a Protestant, so here goes nothing! It's Michael W. Smith's song "Friends."
