Teach by works more than words.
However softly we speak, God is near enough to hear us.
It is love alone that gives worth to all things.
So dearly does His Majesty love us that He will reward our love for our neighbor by increasing the love which we bear to Himself, and that in a thousand ways.
Be gentle to all and stern with yourself.
We cannot be sure if we are loving God, although we may have good reasons for believing that we are, but we can know quite well if we are loving our neighbor. And be certain that, the farther advanced you find you are in this, the greater the love you will have for God.
