do all the good you can

Do good then. Not to do it is to do
evil. A useless life is a sinful life. Act
up to the measure of your light. According
to your light shall be the rigour of your
judgment. Do as much good as you have
done evil, and you will do much. Do all
the good you can. Limit the good you do,
and you limit your love to God, and His
goodness to you.
