The Vegetables and the Weeds

Somebody saw a gardener irrigating his vegetables and said to him, 'How is it that wild plants, without having been planted and without having been cultivated, spring up each season, while the plants that you yourself plant in the garden frequently wither from lack of water?' The gardener replied, 'The wild plants are cared for by divine providence, which is sufficient in and of itself, while our own plants must depend for their care on human hands.'
