St Kosmas of Aetolia: If we want to fare well in this life and to go to Paradise...
If we want to fare well in this life and to go to Paradise, and to call our God love and father, we must have two loves: the love for God and the love for our neighbor. It is natural for us to have these two loves, and contrary to nature not have them. Just as a swallow needs two wings in order to fly in the air, so we need these two loves, because without them we cannot be saved.
If you wish to be saved, seek no other thing here in this world as much as love.
