On Despair
Never despair in God's mercy by whatever sins you may have been bound by the temptation of the Devil, but pray with your whole heart, with the hope of forgiveness; knock at the door of God's mercy and it shall be opened unto you. I, a simple priest, am an example for you: however I may sometimes sin by the action of the Devil, for instance, by enmity towards a brother, whatever the cause may be, even though it may be a right cause, and I myself become thoroughly disturbed and set my brother against me, and unworthily celebrate the Holy Sacrament, not from wilful neglect, but by being myself unprepared, and by the action of the Devil; yet, after repentance, the Lord forgives all, and everything, especially after the worthy communion of the Holy Sacrament: I become white as snow, or as a wave of the sea, by the blood of Christ; the most heavenly peace dwells in my heart; it becomes light, so light, and I feel beatified. Then, indeed, I forget all troubles, anxieties, and the oppression of the enemy, I become entirely renewed, and as though risen from the dead. Do not then despair, brethren, whatever sins you may have committed, only repent find confess them with a contrite heart and humble spirit. Glory, O Lord, to Thy mercy! Glory, O Lord, to Thy long-suffering and forbearance!
~St. John of Kronstadt
