Sins and passions are not a part of human nature ( St. John Climacus )

Sins and passions are not a part of human nature, for God is not the Creator of passions. But He implanted into our nature many virtues, among which the following can be named: mercy (for even the pagans are compassionate), love (for even dumb animals often weep at the loss of one another), faith (for it is natural to all people), hope (for when we lend, sow or labor, we hope to receive a gain from this, and when we travel, we hope to reach our destination). Hence, if love and virtue is inherent in our nature — for love is the fulfillment of the law — then it is clear that virtues are not alien to our make-up. And may those that want to justify their neglect through feebleness, be ashamed.
