Be dead in life, and you will not live in death. Let your soul die strenuously, and not live in weakness. Not only those who suffer death for the sake of faith in Christ are martyrs; but also those who die because of their observance of His commandments.
Isaac of NinevehBe persecuted, rather than be a persecutor. Be crucified, rather than be a crucifier. Be treated unjustly, rather than treat anyone unjustly. Be oppressed, rather than be an oppressor. Be gentle rather than zealous. Lay hold of goodness, rather than justice.

Isaac of NinevehLet there always be a preponderance of mercy with you, even though you don't feel such mercy in yourself, as God has for the world ... A cruel and merciless heart is never purified. A merciful man is the doctor of his own soul, because as it were a by a strong wind from is heart he drives out the darkness of the passions.
