Augustine of Hippo

(de Verb. Dom. serm. lix) For we cultivate God, and God cultivates us. But our culture of God does not make Him better: our culture is that of adoration, not of ploughing: His culture of us makes us better. His culture consists in extirpating all the seeds of wickedness from our hearts, in opening our heart to the plough, as it were, of His word, in sowing in us the seeds of His commandments, in waiting for the fruits of piety.
