"Farming in the world requires the cooperation of four essential elements. A harvest is gathered into the barn only as a result of the natural action of water, earth, wind and light. God's farming likewise has four elements - faith, hope, love, and knowledge. Faith is our earth, that in which we take root. And hope is the water through which we are nourished. Love is the wind through which we grow. Knowledge, then, is the light through which we ripen."
- The Gospel of Philip
