The Corinthian church was a church marked by envy and pride. But in the "dirt" of this church, Paul plants the flower of Love; a flower containing 15 petals, each describing an aspect, or description, of love.
In today's lesson, Paul describes love in the negative, in other words, describing love by what love is not. It is as if Paul is saying to the Corinthian church, "You are envious of one another, but that is not love. You are arrogant, boastful and selfish, but that is not love."
In today's lesson, we contrast love with envy, pride and boasting; that which should not mark the church.
