Such sins, even if they do not kill all grace in us, do harm, nevertheless; and though they are only venial in themselves, they make us apt, ready, and inclined to lose grace and to fall into mortal sin.
Johannes TaulerIf ye keep watch over your hearts, and listen for the Voice of God and learn of Him, in one short hour ye can learn more from Him than ye could learn from Man in a thousand years.
Johannes Tauler
