1. “HE LOVED US”, Saint Paul says of Christ (cf. Rom 8:37), in order to make us realize that nothing can ever “separate us” from that love (Rom 8:39). Paul could say this with certainty because Jesus himself had told his disciples, “I have loved you” (Jn 15:9, 12). Even now, the Lord says to us, “I have called you friends” (Jn 15:15). His open heart has gone before us and waits for us, unconditionally, asking only to offer us his love and friendship. For “he loved us first” (cf. 1 Jn 4:10). Because of Jesus, “we have come to know and believe in the love that God has for us” (1 Jn 4:16).

CHAPTER ONE
THE IMPORTANCE OF THE HEART

2. The symbol of the heart has often been used to express the love of Jesus Christ. Some have questioned whether this symbol is still meaningful today. Yet living as we do in an age of superficiality, rushing frenetically from one thing to another without really knowing why, and ending up as insatiable consumers and slaves to the mechanisms of a market unconcerned about the deeper meaning of our lives, all of us need to rediscover the importance of the heart.

What do we mean by "the heart?"

3. In classical Greek, the word kardída enotes the inmost part of human beings, animals and plants. For Homer, it indicates not only the centre of the body, but also the human soul and spirit. In the Iliad, thoughts and feelings proceed from the heart and are closely bound one to another. [2] The heart appears as the locus of desire and the place where important decisions take shape. [3] In Plato, the heart serves, as it were, to unite the rational and instinctive aspects of the person, since the impulses of both the higher faculties and the passions were thought to pass through the veins that converge in the heart. [4] From ancient times, then, there has been an appreciation of the fact that human beings are not simply a sum of different skills, but a unity of body and soul with a coordinating centre that provides a backdrop of meaning and direction to all that a person experiences.
