Love is infectious, and when human devotion is intelligent and wise, love is more catching than hate. But only genuine and unselfish love is truly contagious. If each mortal could only become a focus of dynamic affection, this benign virus of love would soon pervade the sentimental emotion-stream of humanity to such an extent that all civilization would be encompassed by love, and that would be the realization of the brotherhood of man

Corinthians 13:4-7 (New International Version):

"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonour others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, and always perseveres."
