Forming in our hearts that "root of charity"...

This is a lovely bit from Cardinal Newman as quoted by Fr. Benedict Groeschel in The Virtue Driven Life...

The real love of man must depend on practice, and therefore, must begin by exercising itself on our friends around us, otherwise it will have no existence. By trying to love our relations and friends, by submitting to their wishes, though contrary to our own, by bearing with their infirmities, by overcoming their occasional waywardness by kindness, by dwelling on their excellences, and trying to copy them, thus it is that we form in our hearts that root of charity, which, though small at first, may, like the mustard seed, at least even overshadow the earth.
