St. Theodoros The Great Ascetic - 71 - 73

71. He who is battling to repulse what harasses and wars against him must enlist the help of other allies - I mean humility of soul, bodily toil and every other kind of ascetic hardship, together with prayer that springs from an afflicted heart and is accompanied by many tears. He must be like David who says: 'Look on my humility and my toil, and forgive all of my sins' (Ps. 25:18); 'Do not pass my tears over in silence' (Ps. 39:12): 'My tears have been my bread day and night' (Ps. 42:3); and 'I mingled my drink with weeping' (Ps. 102:9).

72. The adversary of our life, the devil, employs many devices to make our sins seem small to us. Often he cloaks them with forgetfulness, so that, after suffering a little on their account, we no longer trouble to lament over them. But, my brethren, let us not forget our offenses, even if we wrongly think that they have been forgiven through repentance; let us always remember our sinful acts and never cease to mourn over them, so that we may acquire humility as our constant companion, and thus escape the snares of self-esteem and pride. :

73. Let no one think that he endures suffering and achieves holiness through his own powers. For God is the cause of all the good that comes to us, just as the demon that deceives our souls is the cause of all the evils. Therefore, give thanks to their Cause for whatever good acts you perform; and attribute to their instigator the evils that trouble you.
