This Heart is the core of the pro-life movement, which is a movement of self-sacrificing love. Jesus’ Heart has a love first for the smallest and most vulnerable. Nothing can stop the love of the Heart of Jesus, which is the meaning of the flame we see in depictions of the Sacred Heart. This love is met by rejection and hatred, symbolized by the wound in the heart.
Pro-life activists experience the same thing. Our love for the unborn is met with misunderstanding, ridicule, shunning, and persecution of all kinds. Yet nothing can extinguish the flame. We continue to love those who cannot love us back, and cannot even know we love them. And that is a gift of the Sacred Heart.
