i would really appreciate everyone's comments on this one...

reading 1 corinthinas 13, st. paul says, "if i sell all my possessions to feed the poor but do not have love...it profits me nothing."

what is love? more specifically, how do i love God and my neighbor as Jesus commands? if love is not just action, as paul states, and it isn't just a mushy infatuated feeling...what is it?
