1 John 4:12 If we love each other, God lives in us, and his love has been brought to full expression through us.
Love is a gift from God that must be used in order to be useful. The more you love others, the more your capacity to love will grow. The more you sacrifice for others, the more deeply you will care for all people.
You also have the wonderful promise that if you love others, God the source of love lives in you. The more you practice his unfailing love, the more his presence is perfected in you.
The blessing of love is twofold. Love others, and not only will your love grow, but God the spring from which all love flows will show himself more powerfully within you.
