Love has an enormous number of connotations, and if somebody is a person who does kind acts as a way of life, if they are generally disposed to being caring and loving and doing things for other people, then kindness is a much stronger word than we make it out to be.
Kindness is a sort of love without being love.
The New Testament is about loving other people as you love yourself. That means caring for them and looking after them and being kind to them.
