The passage of 400 years does nothing to minimize the wisdom:
Saint John of the Cross, 16th century:
The Lord measures our perfection neither by the multitude nor the magnitude of our deeds, but by the manner in which we perform them.
Mother Theresa, 20th century:
I am not sure exactly what Heaven will be like. But I know that when we die and it comes the time for God to judge us, He will not ask, “How many good things have you done in your life?” Rather He will ask, “How much love did you put into what you did?”
