No one among us can prevail by his own unaided strength over the devices and wiles of the evil one; he can prevail only through the invincible power of Christ. Vainly, therefore, do conceited people wander about claiming that they have abolished sin through their ascetic accomplishments and their free will. Sin is abolished only through the grace of God, for it was made dead through the mystery of the Cross. This is why that luminary of the Church, St. John Chrysostom, says: ‘A man’s readiness and commitment are not enough if he does not enjoy help from above as well; equally help from above is no benefit to us unless there is also commitment and readiness on our part. These two facts are proved by Judas and Peter. For although Judas enjoyed much help, it was of no benefit to him, since he had no desire for it and contributed nothing from himself. But Peter, although willing and ready, fell because he enjoyed no help from above. So holiness is woven of these two strands. Thus I entreat you neither to entrust everything to God and then fall asleep, nor to think, when you are striving diligently, that you will achieve everything by your own efforts. –St Theodoros the Great Ascetic ‘Philokalia’
