“We have many persecutors, both visible and invisible: Impure spirits are pursuing us, as do the heretics, the pagans, and the Jews. All those who want to live piously are constantly under the pressure of persecutions, so much so that one who is zealous for piety can hardly find a moment free from persecution. And perhaps, one can even conclude that when we do not suffer persecutions, it is probably because we are not living piously enough. For if the saying is true that, All who live godly in Christ Jesus shall suffer prosecution (II Tim 3:12)- then the converse is true: that he who suffers no persecution has not yet burn to live truly, piously, in Christ Jesus.”
Saint Ambrose, quoted in Psalm 118: A Commentary by St. Theophan the Recluse, pg. 208-209.
