Jesus answered, "The first is, `Hear, O Israel: The Lord our God, the Lord is one; and you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.' The second is this, `You shall love your neighbor as yourself.' There is no other commandment greater than these."

Mark 12:29-31

 A tree is known by its fruit; a man by his deeds. A good deed is never lost; he who sows courtesy reaps friendship, and he who plants kindness gathers love.

- St. Basil
