+ St. Gennadius of Constantinople, The Golden Chain, 14
Every Christian is chosen—chosen for similar deeds, namely: to be with the Lord, through unceasing remembrance of Him and awareness of His omnipresence, through the preaching and fulfillment of His commandments, and through a readiness to confess one’s faith in Him. In those circles where such a confession is made, it is a loud sermon for all to hear.
Every Christian has the power to heal infirmities—not of others, but his own, and not of the body, but of the soul—that is, sins and sinful habits—and to cast out devils, rejecting evil thoughts sown by them, and extinguishing the excitement of passions enflamed by them.
Do this and you will be an apostle, a fulfiller of what the Lord chose you for, an accomplisher of your calling as messenger. When at first you succeed in all this, then perhaps the Lord will appoint you as a special ambassador—to save others after you have saved yourself; and to help those who are tempted, after you yourself pass through all temptations, and through all experiences in good and evil.
+ St. Theophan the Recluse, Thoughts for Each Day of the Year: According to the Daily Church Readings from the Word of God
“If on coming to the house of a king thou wouldst be apprehensive and concerned not to do anything incompatible with the dignity of the place, then with what reverence oughtest thou to enter into the house of the King of Heaven. If thou art gripped by fear in the house of a king, although he does not see thee, although, perhaps, he is not at home, then with what fear thou oughtest to stand in the house of God, where the Omnipresent One is always present, where the Allseeing One constantly sees thee. When thou hearest a prayer in church, endeavor that not only thine ear, but also thy heart would hear, so that the prayer of the Church would become thine own prayer.”
— St. Philaret of Moscow
