Charity - The Person of Agape
The kind of love that you and I are supposed to be motivated by is NOT a selfish love.
Charity, agape love is not superficial as are eros and philia. It is not often easy, and often challenged, but always rewarding.
People won't remember what you say to them or what you teach them, but they will always remember how you loved them.
1st Corinthians, Chapter 13 tells us how it is, how it should be, and how it will be.
