We must constantly work to learn better how our every act may affect ourselves and others. Genuine moral living involves intelligent love and esteem for our associates. Unless we possess strong affection for others, we cannot come to know that which is most worthwhile in making for the highest character in man. Every narrowing of love, every encroachment of egoism, every act of selfishness, means just so much blindness to that which is good and fine. Let good moral conduct cease to be a virtue and become an involuntary duty.

But the seed on good soil stands for those with a noble and good heart, who hear the word, retain it, and by persevering produce a crop.
— Luke 8:15 New International Version (NIV)
