Love.

"Love is patient, love is kind.  It does not envy, it does not boast, it is not proud.  It does not dishonor 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, always perseveres." 1 Cor. 13:4-7.
