John of Kronstadt
He was born as Ivan Ilyich Sergiyev in 1829. From 1855, he worked as a priest in Saint Andew's cathedral in Kronstadt. Here, he greatly committed himself to charity, especially for those who were remote from the church, and traveled extensively throughout the Russian empire. He was a member of the right extremist Sojuz Russkogo Naroda (Alliance of the Russian people), but did not commit himself politically. He was already greatly venerated at the time he died. He was glorified by the Russian Orthodox Church Outside of Russia in 1964 and by the Russian Orthodox Church in 1990. The second largest monastery of St. Petersburg (by community size) is dedicated to St. John of Kronstadt.
"When you are praying alone, and your spirit is dejected, and you are wearied and oppressed by your loneliness, remember then, as always, that God the Trinity looks upon you with eyes brighter than the sun; also all the angels, your own Guardian Angel, and all the Saints of God. Truly they do; for they are all one in God, and where God is, there are they also. Where the sun is, thither also are directed all its rays. Try to understand what this means."
"There is nothing impossible unto those who believe; lively and unshaken faith can accomplish great miracles in the twinkling of an eye. Besides, even without our sincere and firm faith, miracles are accomplished, such as the miracles of the sacraments; for God's Mystery is always accomplished, even though we were incredulous or unbelieving at the time of its celebration. "Shall their unbelief make the faith of God without effect?" (Rom. 3:3). Our wickedness shall not overpower the unspeakable goodness and mercy of God; our dullness shall not overpower God's wisdom, nor our infirmity God's omnipotence." -- My Life in Christ
"Oh, what great happiness and bliss, what exaltation it is to address oneself to the Eternal Father. Always, without fail, value this joy which has been accorded to you by God's infinite grace and do not forget it during your prayers; God, the angels and God's holy men listen to you."
"The enemy of our salvation especially strives to draw our heart and mind away from God when we are about to serve Him, and endeavours to adulterously attach our heart to something irrelevant. Be always, every moment, with God, especially when you pray to Him. If you are inconstant, you will fall away from life, and will cast yourself into sorrow and straitness."
"Do not be despondent when fighting against the incorporeal enemy, but even in the midst of your afflictions and oppression praise the Lord, Who has found you worthy to suffer for Him, by struggling against the subtlety of the serpent, and to be wounded for Him at every hour; for had you not lived piously, and endeavored to become united to God, the enemy would not have attacked and tormented you."
