Let the tempted one know this: that he himself is both tempter and tempted; that all his enemies are within; that the flatterers which seduce, the taunts which stab, and the flames which burn, all spring from that inner region of ignorance and error in which he has hitherto lived; and knowing this, let him be assured of complete victory over evil. When he is sorely tempted, let him not mourn, therefore, but let him rejoice in that his strength is tried and his weakness exposed. For he who truly knows and humbly acknowledges his weakness will not be slow in setting about the acquisition of strength.
