What is love?

1 Corinthians 13:4-7 (NKJV)

4:    Love suffers long and is kind;

       love does not envy;

       love does not parade itself,

       is not puffed up;

5:    does not behave rudely,

       does not seek its own,

       is not provoked,

       thinks no evil;

6:    does not  rejoice in iniquity,

       but rejoices in the truth;

7:    bears all things,

       believes all things,

       hopes all things,

       endures all things.
