Grant it, O Lord

I have no tears, no repentance, no compunction -- my God and Savior, grant these to me!
St. Andrew of Crete

What is that blessed day? It is the day of self-judgement. When that day dawns, the man who has condemned the whole world until then will at once come to regard himself as the greatest stain on the whole of God’s earth. He will be ashamed before God; he will be ashamed before every man and before everything that God has created on earth. And this shame will begin to burn him like fire. And he will then acknowledge and confess: 'Truly I am the greatest stain on God’s earth. Truly, are all other men not better than I am? …O Lord, Lord, have pity on me a sinner and rescue me from the mire of my sins, that I may so much as begin to resemble Your creation.' My brother, do not expect that blessed day of repentance to come of itself. Take firm hold on yourself the first day that it comes to meet you, and say: 'You are the blessed day on which I shall purchase life eternal!'
St Nikolai (Velimirovic)

Nail my flesh

Let us crucify our member through abstinence; and as it is written, let us be vigilant in prayer, living after the example of Him who suffered; by His passion, putting to death the passions.
Irmos of Matins, Wednesday, First week of Lent

Nail my flesh with the fear of you, O Christ, Who nailed the sin of Adam to the cross. Loose me from the bonds of wickedness, shatter the arrows of the evil one with Your Lance, Master, and deliver me from all his mischief.
Irmos of Matins, Wednesday, First week of Lent

Beloved, our condition needs much endurance; and endurance is produced when doctrines are deeply rooted. ...the soul which is nailed by the fear of God none will be able to overturn. ... Thus the Prophet prayeth, saying, "Nail my flesh by Thy fear" (Ps. 118: 120, LXX.); "do Thou so fix and join me, as by a nail riveted into me." For as men of this kind are hard to be captured, so the opposite sort are a ready prey, and are easily thrown down.
St. John Chrysostom
