How absurd it would be to grasp at money and throw away health; and to be lavish of the cleansing of the body, but economical over the cleansing of the soul; and to seek for freedom from earthly slavery, but not to care about heavenly freedom; and to make every effort to be splendidly housed and dressed, but to have never a thought how you yourself may become really very precious; and to be zealous to do good to others, without any desire to do good to yourself.  And if good could be bought, you would spare no money; but if mercy is freely at your feet, you despise it for its cheapness.  Every time is suitable to cleanse yourself, since any time may be your death.  With Paul I shout to you with that loud voice, “Behold now is the accepted time; behold now is the day of salvation; and that now does not point to any one time, but is every present moment.  And again “Awake, thou that sleepest, and Christ shall give thee light, dispelling the darkness of sin.

St. Gregory Nazianzen
