What is the reason that the angels in heaven have not so much as an idle thought? It is because they are filled with the fullness of God. Take it for an experienced truth, the more the soul is filled with the fullness of God, and enriched with spiritual and heavenly things, the less room there is in that soul for vain thoughts. The fuller the vessel is of wine, the less room there is for water.
— Thomas Brooks (1608-1680)
